Bitcoin :-)

Facebook Stock. Now do you realize how stupid you sound?
He may be mining Bitcoin. If you're able to issue Facebook stock, let's talk :)
Is mining Bitcoin still proficient (except for ASIC makers, huh)?
Mining scrypt coins is proficient. I make $400/month with 2 machines I built 6 months ago.
$400 a month for 2 machines? You should be making a lot more... I just got started a month ago as a hobby, using MiddleCoin pool which converts/paysout in Bitcoin, --w/ 1 high-end gfx card(7950), I'm earning 200/month. I just reinvested 700 to start building out my rig, which will have 5x R9 270's and a hashrate of 2250 per machine. I currently make .0125 per khs per day. So this one machine will be worth $28/day.

I do wish I'd held onto my dogecoins though, I would've made a LOT more if I hadn't kept pumping/dumping.

Must be low end video cards. Two 290x GPUs will earn more than that.
Is that number before or after deducing electricity costs?
The money spent mining bitcoin for electricity and hardware could have been used to buy stocks.

It's not really different, for both mining bitcoins and investing in stocks you need to spend some money. You aren't issuing anything for free.

It will sound banal, but Bitcoins I bought year-and-something ago.
That's not strictly speaking passive income, but capital gains.
That depends, he might be day trading with a bot, that's (largely) passive.
That would indeed be passive income but OP appears to have bought the coins a year ago and has kept them as a speculative investment. Seeing as the wheel of fortune has landed on Tuesday, OP has made a capital gain! :-)
I mined a bunch of coins two years ago but now I mine scrypt altcoins which turn a better profit with GPUs than btc. I also run day trading bots which trade with my cryptocurrency portfolio in general, including bitcoin, litecoin, ad et al.

So at least one person is definitely getting passive income this way, and I'm almost sure I'm not alone.

Please forgive my ignorance, but how do alternative coins work? Who uses them? I've only recently noticed Bitcoins being relatively widely usable, so how does the process work with alternative mineable coins? Do you convert them to dollars at some point or just mine and trade them for good/services?
Altcoins are just another blockchain that uses the basic bitcoin idea of proof of work or stake to validate a distributed ledger, there are dozens to hundreds of them by now and they're all effectively just different distributed ledgers with some modified rules (total coins, rewards per block, demurrage, things of this nature) that are traded on cryptocurrency exchanges like cryptsy with bitcoin.

Because they're liquid with bitcoin they're effectively liquid with all the other currencies in the world, including each other. So you can do things like gauge the profitability of a given altcoin with code and switch your mining based on the current highest daily return, and you can do things like run trade bots that trade into and out of bitcoin and that altcoin depending on various market indicators etc to get the best return on top of that base return, and last of all you can do the same trading strategies with bitcoin and fiat currencies themselves, so it becomes a three layered freelance trading strategy.

To summarise;

* Miners pull down altcoins with raw GPU horsepower.

* Bots trade between the altcoins and bitcoin on market indicators that work best.

* Other bots trade between bitcoins and fiat on market indicators that work best.

I used to just be a coder working for employers directly but this makes me accountable to nobody but the effectiveness of my algorithms. I'm still open to the freelancing side and looking at other opportunities because it is largely passive, but it's the first opportunity I've ever had where I become completely unaccountable to other human beings, and I must admit that has a lot of attraction to me.

I'm a global roaming digital nomad and have been for the past five years or so, but I have always had to worry about being contactable by my clients and timezone shifts and things of this nature, now that doesn't matter so much as I don't even need to talk to anyone at all if I don't want to. After finally achieving absolute complete communication disconnection with the entire rest of humanity though I am starting to feel the slightest inkling of what I have constantly heard other people talking about with feeling something missing in not being in the office and interacting with others all the time.

It's a crazy world, and I'm a crazy person.

Wow, your post became very interesting to me in the last two paragraphs. Have you considered joining organizations that do make demands on you (and hence keep you connected to society), but not for financial reasons? Social clubs would work, but I would expect more meaning would be found in community service, religious organizations, artistic projects, etc.
The thing about human contact for me is that I can do with very little of it, that it takes this magnitude of isolation for me to even identify with the idea that people might actually want to socialise with other people is emblematic of that.

Every two or three months I attend a local meetup, or try to arrange contact with some of my old friends that travel frequently enough that our paths nearly overlap, that's basically enough for me I think. Perhaps that will change in the future but for now it's certainly the case.

Are you offering IAP?
No! Thats the funny part.. I am putting only IAds..
Nice! That's worked out well for you - congrats! :)
Not much has changed since the last thread. Improvely (https://www.improvely.com) is still in the 5-digit monthly RR range and growing, and I do no outbound marketing other than some PPC ads that don't need much active management. Everything that can be automated has been automated (onboarding, lifecycle mails, dunning mails for billing issues, etc), leaving me free to spend all my time on support and improving the product.

Two things that fit the "passive" mentality that have been picking up steam recently:

1) I offer an affiliate program with a revenue share commission (upfront bonus plus 10% of the referred customer's payments for a year). A couple of my best customers have become my best affiliates, recommending the product on industry blogs they write for regularly. It doesn't get better than having excited customers marketing your product for you. In the early days the affiliate program wasn't doing much at all, now it's a meaningful contributor to subscriber growth.

2) I've been running Improvely long enough now (just over a year) that some of the clients are growing their businesses significantly. I've got quite a few marketing agencies on board, and they're picking up new clients and adding them to their accounts. As their business grows, and their usage grows, they upgrade to plans with higher usage limits. Same customer base, higher revenue per customer. In the beginning, a new customer was worth $30ish per month. Today that's over $70/m per customer on average.

That's great Dan. I have a couple of questions.

Do you have an in house affiliate program that you use or a third party one? How did you get affiliates interested (other than existing customers)?

It's run through ShareASale [1]. They take care of tracking sales, cutting checks, sending 1099s at the end of the year, and all the other boring parts of running an affiliate program. As for getting affiliates interested, there's a link to the program in the footer of the site and a link within the app for existing customers. When I come across a site that seems like it'd be a good fit for some kind of partnership, I just send a brief e-mail and see if there's any interest.

Oh wow, this looks like exactly what I've been looking for for my not-so-passive income project, textbooksplease.com, for tracking conversions.

...any chance of an HN discount? :D

(comment deleted)
Hi, I was checking out your project. Do you mind if I ask where you got the list of universities and the URLs?
Hi Christian - textbooksplease looks great. nice job! I was wondering: 1 - how do you monetize? 2 - how does the post-stickers-get-tshirt marketing channel perform (and how do you know, as it's hard to track..)

cheers!

Thanks! :D

1. Affiliate links. Each time someone buys a book through my site, I make ~5% from the retailer.

2. You know, not very well, but I think its a cool perk to give to customers you interact with ("glad I fixed your issue - want some free stickers?"). My biggest ROI to date is from google adwords, but they're outrageously expensive, so I'm going to be focusing on natural SEO for this next semester.

Congratulations! Any tips on what worked the best for you to grow your product?

(I have a product with 4-digit monthly RR and I would like to take it to 5.)

Awesome, congrats.

Just putting this out there: if you're generating that scale of value for agencies, you can often get them to agree to an arrangement which sounds like "$X per account you rep". Mental comparison for you: what's the largest agency you count as a client paying you? Would $250 times the number of accounts they rep be a substantially larger number than that? They probably make substantially more than that.

My brother works at a PPC agency. Typical client: a company you've never heard of in Chicago which does, without loss of generality, weatherproofing. They have a PPC budget of $IT_WOULD_BLOW_YOUR_MINDS_HN. Like many PPC companies, they charge (WLoG) 20% of spend every month. $250 doesn't make that account meaningfully lucrative and if you give them 1 extra conversion a month to brag about it's net profitable for the client.

I am aware of other marketing software companies which get into very cozy relationships with their favorite marketing agencies, to the tune of four to five figure checks monthly. That would, presumably, lift your average from $70 to an even happier number.

Bonus points: if you do it right, you can pitch this as a straight moneymaker to the agency, on some model like "You add a line-item to all your invoices of +$500 for $FOO_SOFT, so after we get our cut, that's $12,500 that your agency grosses which is totally free money to you."

How did you manage to compete against google analytics (which does conversion tracking and a lot more, for free) ? Conversion tracking is something that i thought became a dead market at least 5 years ago (at that time i developed an analytics and conversion tracking solution myself).
I think Google Analytics dashbaord can be confusing and cumbersome. I understand that once you've used it and understand you can be proficient at it but many people don't have the time or care to learn the a complex tool.

I think the biggest value proposition Improvely offers is the Click Fraud reports/reporting and alerts.

Dan, I love your date range picker. I use it all the time. Thanks.
second that. Using it as an angular directive. It's really nice!
This is a super cool product, I'm giving it a shot.
I'm having trouble figuring out what you do. Or rather, I know what you do, but am not sure how you do it. How do you track conversions?

I couldn't find a page on the site letting me know how much technical skill I'd require to implement this.

Silly question, What is "RR"?
"RR" is recurring revenue.
Just in the middle of getting this up (was a way of teaching myself Rails) that works as an Affiliate style site for gadgets and cool gift ideas. http://fmhgifts.com/
pretty cool. how do you syndicate products? through amazon's API or by hand?
Currently by hand but literally every single aspect of that site is entirely outsourcable to college students who would cost me much less than the cash that an affiliate site with even relatively low traffic would expect to make organically.

Once I have 200 or so products up there I will do some much more interesting stuff with it.

I like the design and the idea is smart, but are you planning to monetize this?
Only makes money via Amazon affiliate links which aren't a horrible gig if you get even semi decent traffic.
My iOS app that teaches you what a tesseract is and lets you manipulate it in 3D and 4D.

It blows my mind that people still find out about this app and happily buy it every day even though it occupies such a small geeky niche.

Seems to violate the premise of "the dumber the app, the more popular it will be." Awesome.
"The dumber the app..." works almost everytime. I launched a conceptually great app which was a complete failure: https://itunes.apple.com/in/app/gravity-byte/id504372023?mt=...

Then launched a card game which is a decent success..

Gravity Byte may be a great app. But, it does not make a great first impression. You may want to try to give the app a more cohesive art direction. For example, in the app screenshots, I see 4 different fonts. Also, the game graphics don't really grab my attention. Keep in mind that most people are judging your app almost entirely by the screenshots.
You could probably turn that around rather easily by paying a good designer or graphic artist to produce some professional looking assets and reskinning the game.
It's a shame, the icon for Gravity Byte looks really nice, but then the screenshots put me off instantly.
That looks so cool. I'm glad it brings in a good amount of money.
Heard about this app when it first launched, such an original idea.

Would you feel comfortable telling us the number of sales in 2013?

The Fourth Dimension generated $17,600 during 2012, the year I launched it. The majority of that was driven by reviews the app got.

In 2013 it made $3900, or $325/month, and seems to be holding at that rate of income. The only work I did on the app in 2013 was about two days making it work correctly on iOS 7.

It's not huge money, but it's far more than my expectations, which were on the order of $500 total over the lifetime of the app.

I posted a breakdown of the first three months of reviews here: http://www.fourthdimensionapp.com/first_three_months/

My next app is a two-player Tetris/Scrabble mashup: http://fiascoapp.com/b

My expectations for the word puzzle game are either $300,000, or zero. The wave function has yet to collapse.

From the reviews, it sounds like the high quality of your explanations has made a small geeky niche far less small, geeky and niche. Bravo.
The app icon is irresistible.
Thanks. It was essentially my son's idea (age 5 at the time), and it was about a month after I designed the icon that I realized the "third eye" connection, as in http://en.wikipedia.org/wiki/Third_eye which made me love it even more.
Cool! My mom showed this to me (she's a maths teacher) In fact it was the first app she ever bought! She just loves showing it to all her science colleagues! That really is an awesome app!
I love hearing stories like that, thanks. I never thought it would resonate with so many people.
Nice! WRT to the icon, you should add stereoscopic imaging (red/green style) to geek out even further!
Near the end of the app, there is a cross-eyed stereo viewing mode that works pretty well, although it can be headache inducing for some people.
I'm really looking forward to your next iOS app, Fiasco -- it looks awesome. I hope you don't get sued for Scrabble kicking Tetris in the face, or by Stanslaw Lem's estate!
Wish you had an Android version :/

Kudos anyway, great idea and looks like a great execution as well!

Income is often called passive but essentially there is always something you need to do, monitor, improve or change in order to keep cash flow steady. If you don't, your income will decrease over time until reaching zero. It is surely easier to maintain "passive income" than to start from scratch.
I understand 'passive' to mean 'charging more than once for the same piece of work'.
I interpret "passive" to mean "not directly trading time for money".
I've got a job where i do almost nothing. It's my passive income.
Do some freelancing during office hours & double the income.
This would not be passive.
You have to think bigger man.

Outsource the outsourcement... Interact with top-level outsourcer once per week... he interacts with low-level outsourcer daily.

Profit.

Yes, but how i would outsource interacting to still do nothing?
Relevant: "Man reportedly outsources his own job to China, watches cat videos" http://articles.latimes.com/2013/jan/17/business/la-fi-mo-ma...
That's as timely as awesome
this may be veering off-topic, but why would an employer-- especially a big one with lots of individual consumers as customers-- be willing to make it publicly known that that occurred?

doesn't it undermine consumer confidence in their business?

They didn't. The story is provided by Verizon's Enterprise Security Products group, and is a cautionary tale about one of their clients and the need for proactive log review. The client and the cat-loving software developer in question were not named.

Original source: http://www.verizonenterprise.com/security/blog/index.xml?pos...

While not doing anything might be immoral, doing something else is most likely in violation of the contract and the work done would (again, most likely) be owned by the employer. Along with the income.
You're risk adverse, aren't you?
Yeah, what are you, chicken?

I'm not a chicken. You're a turkey!

Government or big co?
I'm convinced this is the best type of passive income. A job with minimal work (perhaps some kind of security guard or IT support) sitting at a desk. I would use the opportunity to work on my own projects that would actually make me money, all the while getting paid.
Yeah I want this.
I had this, it got boring real fast. The money wasn't great. I could live on it but there was no future prospect. A slow career death if you will. So I took a harder job, with higher pay.
This, I had the same issue, except they paid well. I ended up leaving for a job that would actually use my skills with more pay
Exactly the same case for me too. At first it seems like it would be great, but it was wearing away at the passion I once had for my career. I now spend my days looking at cat videos and playing games rather than focussing on personal projects. I move jobs in 2 weeks to a harder job with better pay and can't wait.
Best of luck with that. For me it was a great decision!
Can't really argue with "and higher pay"
It was exactly double. Can't argue with that.
Like others have said below you think you do and you do for a while but then it starts to wear on you, big time. All that extra time you have at work becomes oppressing and personal projects suffer if you work on them at all. I'm looking to either go back to school or find a tougher job, I've even considered landscaping or construction since it's generally non-stop but it would be a detrimental pay cut.
I work for a big company where there is a lot of down time. It may sound appealing - good pay with minimal to no work, along with minimal supervision - but it get boring real fast and can be demoralizing.

I would rather be actively working on something that challenges me, than have my brain rot away.

I've even tried working on side projects while at my day job and it doesn't work out because it's difficult to really devote focus to something that isn't related to your job.

Microsoft? Meetings are work man!
Hmm, I probably should send my cv there...
Do you have to show up at any particular place every day?
Morning stand-up meetings and the office kitchen.
I've got to say it ain't so easy to find such a job. When you've got some qualifications, employers doesn't keen on hiring you. I'm talking about tech support jobs that you can do easily during the day. Working as a night guard is usually very low pay and doesn't justify the effort. If anyone has got an idea on how to get remote flexible support jobs, I'd be happy to hear.
If you're looking for some dropshipping insights (which the OP's link suggests), here's a nice story: http://www.ecommercefuel.com/selling-an-ecommerce-store/
That one's interesting, but leans more towards the "part-time small business" side than the "passive" side imo. Manning a phone line 4 hours/day M-F in particular makes it at least a part-time job, since you can't do that and also be traveling, holding another job, or studying full-time.
Nothing as of yet. I used to receive donations from my blog and some Windows programs I've written: http://www.softpedia.com/developer/James-Brooks-12392.html but that seems to have dried up. I probably generated £100~ from all donations.

I'm now working on several iOS (http://james.brooks.so/contare-my-first-ios-app/) applications (paid) however I do intend to offer free versions with iAds.

I've also got an Android app on the Play Store that's made me a few quid; https://play.google.com/store/apps/details?id=com.jbrooksuk....

Apart from my iOS applications now, I intend to develop some SaaS apps that I can use to generate some more income.

SearchTempest.com got to the point where it was my main gig about 5 years ago, although it's since leveled off. Like anything, you end up being pretty active if you want to continue making that "passive" income. :)
I've used this on multiple occasions! Awesome site! Do you mind revealing how much it was generating?
I'd rather not get into specifics, but between SearchTempest and AutoTempest, we've bootstrapped up to a team of four. My goal isn't really to get huge or make a pile of money though; mostly just want to keep it going and being as useful as possible, while keeping up with the times. (We really need to get the sites working better on mobile devices; getting ready to release a fully responsive AutoTempest soon...)
I'll try to start an ecommerce for France, following the other ones who specialize themselves in just one kind of well made product, like socks (www.archiduchesse.com), or underpants (www.leslipfrancais.fr). Coming soon ;)
Excellent, I had heard about leslipfrancais, but not the socks one =)
Owning a flat in Moscow and renting it out? Easily 1000$/mo. You can live in Thailand on that money.
High-end flats in Oslo rent out pretty well IIRC. Just have to front some cash to buy the pad.
A lot of people inherited flats from after soviet union times (where you lived in, you now owned after filling some papers) plus some people bought them when prices were affordable (if you had influx of hard cash) plus people tend to buy flats because rent market is unreasonable.
Until housing prices fall 1% before inflation and wipe out your gains for the year.
It's a long position that pays dividends. Why care about volatility?
It's fallaious to not consider the market value of your assets as well as any income streams. In fact, this example is even worse because it also doesn't consider the cost of capital and fluctiations in the income.

For the specific example of buying apartments in Oslo to rent out, sensible analysis will show that this gives a worse risk-adjusted return than other options (e.g. the stock market). But hey, go right ahead. It's not my money ;)

Stock market is prone to crashes; also you can't live in your stocks when out of other options.

If you believe in long term economic stability, then go ahead and invest in stocks. We don't. And now we know at least we'll have a place to live.

When economy is stable, realty prices grow; when economy is shaky, realty prices fall but slower than stocks. Stocks are more liquid on the other hand.

Or worse like where I live (Switzerland), people rent flats, then subrent them for a lot more and go live in Thailand (or somewhere else). And then we all complain because the prices for (renting or buying) flats is insane here.
(comment deleted)
The final price is determined by supply versus demand, not by the number of subrenters in chain.

The real problem in your situation is that these people are able to rent flats for sub-market prices. But it's not your problem. Your problem is that you don't have enough realty supply. And/or more people who want to live in interesting city than interesting cities of Switzerland can house.

The latter seems to become a major problem in most countries.

Don't know about EU laws, but in Russia every apartment rent agreement I've seen (which is statistically insignificant amount, maybe 4-5 agreements) had explicitly prohibited reselling/subrenting.
Same in Bolivia. You're even explicitly disallowed to rent rooms out to people unless you notify the owner. I agree with it to, if I were to own an apartment and rent it out, I wouldn't want any random person to live in my home.
(a) Switzerland is not in the EU. I have no idea if some other Swiss law might ban it.

(b) Switzerland is crazy expensive. So you can probably make megabucks renting out property there.

I am from Switzerland as well and to do such a thing would be illegal and I haven't heard of people doing it...
How nice is living in Thailand? Quality of life wise, people wise, tech wise?
I never tried to do it myself but many people spend winters there. Or even telecommute from there. I guess it's a place to live cheaply by the beach. Cuisine is also nice as I've heard.
I created and sold Stickonspy (http://stickonspy.com) just after mid last year. The initial month I launched it did pretty well as the NSA news was still a pretty big deal. All in all it's made me < £1k but it's been great fun to build and ship a product from scratch. I've shipped to around 12 countries too which is cool. I also spent no money on marketing.

I'd say my time - which was evenings after work - investment was around 3-4 days initially and then fulfilling orders is simply writing a customers address and posting the stickers - which if the demand was bigger I'd probably outsource.

It's been great. I've learnt a shit tonne & the conversations it started has given me an idea for a similar product which I'll be focusing on very soon!

I like this - it made me chuckle :) Can I ask who you used to print the stickers?
(comment deleted)
Great idea. Just wondering that if you didn't spend any money on marketing, how did you get the word out, SEO?
I started out by merely tweeting a link to the site and asking my friends to do the same. I did publish HN but it got took down pretty sharpish.

My main win was cold-emailing tech blogs. I got featured on BoingBoing - http://boingboing.net/2013/08/12/stickonspy-sticker-reminder... - through emailing and also managed to sell directly to Cory ;).

I made this PHP library about 5 years ago:

http://zervaas.biz/escapianet/

Probably make 2-3 sales/yr which is always a nice surprise. It comes up first when you Google "escapianet php"

I also wrote a PHP book in 2007. I still get royalty cheques, although they've almost approached 0 - the last quarter was about $30 ;)

Most of my income now is from app sales.

I had created http://notationtraining.com in 2010 when I was learning how to play piano. I did update this project few times, but otherwise it is completely on its own. It makes only about 300 USD/month but I am quite happy with it as I am not doing anything to promote it or anything else.
Wow, very good job. Did you think much about SEO when you set it up?
Not really, I create first version in about 5 hours and only marketing I did was to post it into Chrome web store and I was really surprised that people actually using it few days later
My book "Mastering Modern Payments: Using Stripe with Rails" continues to sell well, in the $2k range per month. It's not exactly passive, though, as I write blog posts and develop other related content in the same theme.

https://www.petekeen.net/mastering-modern-payments

Ever thought about rewriting parts of the book to work with other languages, as a separate product?
Yep. Language and payment processor variants are something that I've thought about a lot and will probably start working on at some point.

Edit: autocorrect correction

PHP would be a natural fit (Symfony2 or Laravel 4 (I'd vote for Laravel 4 as that is a rapidly growing market that is still relatively "poor" in learning material).

Also if you did happen to do it for Laravel 4, I'd buy it ;).

Wow, I just took a look at the docs for Laravel. I had no idea it was that sophisticated. Thanks for the tip, I'll look into it some more.
It's a truly excellent framework that pulls in the best in breed from the others but then puts a layer over the top that allows you to get things done (in a well engineered and testable manner).

The framework creator (Taylor Otwell) has an excellent book on leanpub and there is an amazing video guide site (laracasts.com) which is better than I have seen for anything (check out the free vids for an idea of quality).

I have a quite simple web site with some calculators for taxes and stuff, that I originally built in 2007. The Google AdSense and affiliate income has grown from about $1000 per year to almost $1000 per month.

It is "passive" in the sense that I respond to the occasional e-mail (once a month), update the data once a year, and add another calculator when I feel like it.

A few years back, I was in the same position with another (online casual gaming) website, that I sold for 2.5x the yearly revenue. Looking back, I should probably have kept that site as well.

Pro tip: quality content beats SEO in the long run. Be the tortoise.

Can you tell me which site it is?
Sure, but the site is in Swedish: http://rakna.net
Ah I actually ended up using that a few months ago when trying to determine cost of living between various European countries. I was pretty shocked and saddened (as a naive university student) when I realised the full extent of taxation in the UK for graduate job salaries but soon realised it was still less than those of Europe, especially the nordic countries.
Any reason why you haven't done an English version?
It looks like it has some Sweden-specific stuff, and adding in English-speaking countries would require knowledge of their tax systems. I suppose you could do an English version for English-speaking people living in Sweden who don't speak Swedish, but it would likely be a tiny niche market.
No good reason, no. Feel free to start your local franchise, and let me know how it goes. :-)
Wow, funny that a local version can make so much money... Maybe I should be creating somthing simple but usefull too... Sometimes we software devs think we have to create something complex in order to get money... But you just have to solve a simple problem people have. Thanks for the insights!
1) Selling Elon Musk t-shirts: http://www.zazzle.com/elonmuskspaceman Did not make that much but was great fun.

2) Helping my artistic friends selling their products. If you want to sell designer products, you can sign up here: https://docs.google.com/forms/d/1dmyfzRwBbpcKAyRplHs0i2RMqsC...

I'm a huge fan of Elon Musk, but I must say I don't like the designs very much. I you can't make better designs, you should think of having shirts with quotes like “If something is important enough, even if the odds are against you, you should still do it.”or "I'll put a man on Mars in 10 years. Maybe 20 years worst case. Otherwise I won't be able to go there." (can't find the exact quote!)
Thanks for the tip. Just added some t-shirts with quotes. The goal is to create more designs in the coming weeks.
Haha I love the "I would like to die on Mars. Just not on Impact" I didn't know that one!
My app and side project "lolipop". An "instagram for gifs and funny images"-niche app. 100k + downloads.

Gotten hugely popular in Norway. Released a revamped iOS 7 version to the US last week (?). Things are going slow over there. Not even reached 1000 downloads.

Traffic always spike during 23:00 - 03:00 when kids should be sleeping... 99% of users lurk and browse reddit/9gag/imgur some contribute (no account needed for browsing).

How does this generate income?
Users get a "pro account", much like the Twitter Verified badge (called lolipop AWESOME) for a week if they "Download a free app". Those pays everything from 20 cent to couple of bucks per download.

App runs barely any hosting cost, and this generates a nice little passive income. I have an admin panel to turn on more ads, but as of now I would rather grow with as little intrusive ads as possible. When, and if I turn on more intrusive ads, users can purchase a "pro badge" to get rid of ads. (turned off now).

Best side effect is that I have gotten a LOT better at obj-c development since I started playing with it, and now run a small mobile development company that actually pays the bills. Learn while you play :)

This is awesome! I'm teaching myself Obj-c now and would like one day to take it further. Glad to hear that it's working out for you :)
Best of luck :) If you have any questions, be sure to ask. I started with the Stanford videos on iTunes u. High quality stuff!
http://pressbulgaria.com - it is a SaaS for sending press release to the media. This tool gives the citizens a lot of power to ring the alarm on certain problems. Also my customers use it as channel for promoting books, exhibition, events, etc

We have a tor hidden service for anonymous submissions. We offer free service for whistleblowers, that want to stay anonymous (and can't pay us).

Great idea!

What percentage are paid users versus free anonymous submissions? How long have you been in business? What are you profits like? Thanks

I started wcfstorm (http://www.wcfstorm.com) about 4 years ago. I started out with just 1 product and has now added 2 more. The income is pretty nice. It usually exceeds my monthly salary. I love it when some stackoverflow users recommend it to others when a question gets posted about WCF testing.
Great product! I used it a ton when I was .NET programming. I used wcfstorm to load test our API to show response time degradation.
I know this isn't entirely passive, but I occasionally rent my spare room on AirBnB. I'm quite clear that it's a basic room and if they use the kitchen etc. they need to clean up after themselves - this isn't a hotel I'm running... So there's basically no work to do other than cleaning the bedsheets, which I do as part of cleaning my bedsheets anyway... I do this for a maximum of 1week/month, which gets me roughly £4000/year and since it's tax exempt in Scotland (under lodger laws), it's the easiest money I've ever made.
Sounds like it's treating you well but have you had problems or do you price it so you generally price-out those that might less than savory characters?
I live in a city that lacks hotels and doesn't have any tourism, so the only people contacting me are people who work in our local industry (offshore oil production), and just need a place to stay while they are doing training, etc. I've never had any problems, and like I said that has kept work for me really low.

In terms of pricing, I just priced it by what I thought was fair. I do refuse people though, since like I said I wouldn't host for more than a week or so per month (I don't want this turning into a job, but it's the easiest money anyone can make if they have a spare room).

I created the app 3dweapons for Android about 2 1/2 years ago. (http://www.3dweapons.net) The free version was downloaded >1.7 million times. The paid version around 8k times.

I added adds from multiple sources (mopub, admob etc) and in app purchases.

For the paid app: In the top months (2 years ago) I made around 800 euro. But it dropped to 90 euro per month currently. For in app purchases: I am making 30 euro per month currently. For ads: Making about 200 euro per month currently.

Oh man, you should be making more money. Great fun app!
Do you have a way to tell how many of your paid installs are legitimate?
See how much Google sends you every month?
You are referring to the pirated versions of my app? Actually i dont have hard figures.

Initially I was not aware of pirated versions. I even had my app translated to chinese because I thought it would be a huge market. But after I did that, i noticed Google Play is not active there, and all paid apps are free in china.... Pirated versions.

I tried to prevent pirated versions of my app by performing code obfuscation, but probably it was still easy to crack.

So another 3 months to buy a Motorola Xoom ;-)

Are you planning an iOS version?

Hahaha Emiel! (I worked with him for over 2 years). I can give you a link to the source so you can implement it in objective-c. I'll buy you a beer!
