FWIW, I found the Wolfram|Alpha paid app for android to be everything I need as a "calculator". The permissions don't seem excessive, although it does use GPS it does not slap ads on me.
Unfortunately, it needs internet to work, and the keyboard IMO doesn't work that well, I keep mistyping stuff, which doesn't happen with the regular keyboard.
To be fair, his points in the article are 100% valid. However, it would have been nice if he gained legitimate users and reviews, not just those adding reviews in spite of the opposition.
Well, what he's done is clever, but perhaps ever so slightly unethical.
If he genuinely just cared about users he could have reported the issue without pushing his product. Mind you, I can't blame him from mentioning his app, it's a great chance for publicity.
He probably didn't know he was going to get so many dodgy reviews/users up-front. Nonetheless, the appropriate thing to do now would be to edit the original post. State that he appreciates that privacy conscious users agree this is an issue and he is glad people have downloaded his app. However, he's after genuine feedback so that he can further improve his app - as such could users please ensure they try his application and only then provide legitimate feedback, either via Google Play reviews or another contact mechanism.
I think that would be an appropriate edit to make. In the beginning, I think it's fair to have the disclaimer that he has an interest in a competing app. So should he do that without naming the specific app he's working on? That might carefully walk the line.
if he didn't mention his app as a disclaimer and when users find out about it (which is bound to happen), they will go apeshit. I think it's a smart move by the author. he gets his publicity and get a chance to slam his competitor.
A questionably legal but terrific calculator is any TI-8x emulator for Android. I think as long as your own a real TI-8x and extract the ROM yourself, you can legally use the emulator. One of the emulators is called "Andie Graph".
Well that's the question good calculators have quite sophisticated "rounding error" fixes that ensure that large calculations don't end up being off by a light year, it's not just a simple question of rounding up/down because if you always do that staggering errors or even a short calculation with a large exponent can throw you quite a bit off.
On a serious note, you have to admit that the familiarity of the calculator helps. I don't know how much you're crunching numbers for complex calculations, but trying to get them to work on Wolfram Alpha or some other web calculator can be near impossible.
It gets even sillier, despite having permissions that resemble malware it is correctly classified as suitable for "Everyone", the most lenient classification.
I have the same HP11C I bought in 1989. It has hardware buttons, instructions on the back, and RPN. Needs batteries about once every three years of heavy use and fits in a pocket. Get off my lawn.
On the other hand, I already have a powerful computing device in my pocket, capable of providing an extremely flexible interface (admittedly not with physical buttons). Why should I carry another object just to do maths?
When I need to do a math as part of my primary activity, I use my HP12C. In part that's because it is easier for me to use a dedicated device, even in the field, than to wade through an app store and it is more pleasurable for me to use something that is advertising free and more intellectually satisfying to me to not share personal data with advertizers when I perform calculations.
I didn't say anything about what anyone else should or shouldn't do.

Bit pricy but it somewhat easier to navigate than HP-48. Though it has limited RPN support...

Alas, nowadays it's overkill. A bit like a Mack truck, which you use to drive 300 metres down the road to buy a pack of cigarettes.
It's still one of my favorite gadgets, though.

(or privacyguard if you have a custom rom)
If you don't have root, you don't own your device, someone else does.
(just wish the xprivacy ui was as easy as old CyanogenMod was, simply strike through the privilege to revoke)

Simple Metronome by Ethan Brown does what it says without asking for ANY permissions (as it should).
God help you if you're looking for a flashlight app.
Shazam, for instance, is beaming back significant location changes and each time that you pass a BLE Beacon within its network (among other things).
