Macrocodex - Guaranteed weight loss or weight gain within 2-3 weeks, beating GLPs for weight loss! https://macrocodex.app/ 17,000+ users already.

Back in time, many people used to say, "I am genetically predisposed to fat or underweight" All of them were proven wrong by macrocodex's method.

No matter if your metabolism is slow or fast, most people will see guaranteed results!

tech stack: flutter and rust

I see the claims, but I don’t see any evidence supporting them. Could you share what you’re basing the guarantee on? Do you have any publicly available data showing that your app delivers guaranteed results and outperforms GLP-1s? I searched and couldn’t find anything supporting those claims.

Well, I know you work for Macrofactor, but we are not interested in producing useless posts with colorful charts.

>Do you have any publicly available data showing that your app delivers guaranteed results and outperforms GLP-1s?

Yes, our group has thousands of members and where people can join the group through the Macrocodex app, they'll see Macrocodex users outperforming GLP users.

Greg Nuckols can't even do math well. Look at their subreddit, people are always having issues with their app.

As macrocodex is beating macrofactor by a long shot, many people are realizing that Greg Nuckols's science is more about marketing than results and evidence!

Do you remember the Hussain and Solomon controversy of Jeff Nippard, one of the top MacroFactor promoters? And the PhD controversy of Mike Israetel?

MacroFactor charges $72 a year and spends a lot of money paying influencers to promote the app, so it’s not surprising that you see so many submarine posts about it.

Very soon, everyone will realize this!

The basis of these apps is pretty simple: you have to adjust your calorie target based on changes, you have to re-calculate as you go.

What I've found is that tracking activity via calories burned is horribly unproductive as there are large variations on how many calories were "burned" depending on the app, device and activity. Are there any scientific studies on how to calculate calorie burn for any activities? Anything in a controlled environment to understand something simple like adult walking 1 flat mile at 3mph. It seems like this would be really hard to nail down compared with say average calories in an apple. Anecdata: as soon as I stopped tracking activity, the scale started moving.

Equities lab, www.equitieslab.com. do robust quant fundamental analysis and back testing easily. Definitely small. Tech stack is java, cython, numba.

Congrats on the 700. Genuine question: how did you land on the current price, and have you ever tested going up? In my experience the first price a bootstrapper picks is the one they'd pay themselves, which is almost always too low.

I'm working on a small SaaS to archive web pages. It's still very early stage. So far there's a chrome extension and RSS feed reader. I'm still working on some more interesting integrations.

At the moment, it's not really a monetize-able product because it's so niche, and competitors are well established. My goal is to have stable, consistent pricing for years (hopefully decades), while also making it easy to switch to self-hosted alternatives.

Stats: $0 MRR

I never thought anybody would pay for this. I have it locally, no need for sass. And it hits into my zettlekasten. Even the people I know that have a use for this, are unwilling to pay and they rather suffer copy pasting things. It seems more of a feature than a service imo so the integrations would be the interesting bit. Best of luck!!

"Not really monetizable yet" is usually a positioning problem, not a product one. Web archiving for everyone is hard to charge for. Web archiving for one group with a compliance or legal reason to keep pages (agencies, journalists, e-commerce teams tracking competitor prices) is very chargeable. Who's using it today?

I made a notepad, which is also a shared memory layers for all of the agents (claude, gpt). So wherever you talk, you're saving important info without efforts. It gets saved & organised on its own.

Its called Lapse (lapse.in) & its completely free

Using it is pretty simple → Simply close your eyes and imagine the micro-scenario until you hear the next one (such as: moonlight on a white flower).

Default session duration is only 7 minutes (try this out tonight!)

People actually bought version 1, and still use it, but its mostly free users. Its hard to get people to pay anything.. but i did make about $1000 from v1. People still use it everyday, even though its not AS useful as it was before since agents have improved but it comes in handy.

I can't even get anyone to try buttons cli for free lol, I use it though, to see what codex is doing in terminals (and I like clicking buttons and being able to generate commands faster than googling) https://buttonscli.com/3/

I am building a life management FOSS app, to take care of basically all needs of the modern 21st century average citizen. https://github.com/ontoplano/ontoplano

Planning the week, general tasks, establishing goals, recording inventory, habits, workouts, bills, setting up reminders... you get the idea. I designed it to have a smooth UX, to work on my mobile phone, to be easily customizable, pretty-looking, and also to have a MCP server so I can talk to an AI and have it update stuff there for me (which works already!).
