1. Favourite RPN calculator app, main use case being quick short maths (like simple budgets etc), where getting my proper calculator would be too inconvenient.

2. EDIT 2021-09-29: Thanks for the fix!Perfect, a modern, minimal RPN calculator that can be used as a drop-in replacement for the Android calc.

3. -im not sure about the necessity of both a drop and a delete button, they seemingly do the same thingOverall, an excellent basic RPN calculator.

4. Could use a more attractive app icon, though.Why did the drop, swap, delete and clear buttons got symbols now? They are confusing and weird, it was much better with text.Very nice, best rpn calc found so far.

5. Like why is it that when I input a number like 1274.08 enter 1227 minus, the result is 47.079999999999.... and not 47.08??Don't know why I can't edit my last review, but I want to stick to my word.

6. The only thing missing are a few operators, notably logarithmic ones.Nice to have a basic RPN calculator for my smartphone.

7. My main issues are: - The exp button should be renamed to EEX (enter exponent), as on physical calculators "exp" refers to Euler's number.

8. I guess it doesn't really do much in the way of explaining how RPN works, but let's be honest, you wouldn't be reading this review if you didn't know what RPN was lol.It looks clean, it's ad-free, it uses no permissions, and it's RPN.

9. I do have a bit of an issue with the roundoff error that keeps showing up: e.g., type 9, then [1/x] twice, and you get 9.000...001etc. It happens on other calculations too, like square root.

10. Just one issue: at a larger font size, the last row becomes tiny and almost unusable.Perfect for everyday use.

11. The large keys and perfect layout makes it easy to use and has extra math functions to put it a cut above the rest.It's great.
