Favourite RPN calculator app, main use case being quick short maths (like simple budgets etc), where getting my proper calculator would be too inconvenient. It's simple,and unburneded by extras like sin, cos, tan. The interface is really good for quick maths. My main issues are: - The exp button should be renamed to EEX (enter exponent), as on physical calculators "exp" refers to Euler's number. -im not sure about the necessity of both a drop and a delete button, they seemingly do the same thing

Overall, an excellent basic RPN calculator. 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. EDIT 2021-09-29: Thanks for the fix!

Perfect for everyday use. The best RPN calculator to replace the standard calculator on your phone. The large keys and perfect layout makes it easy to use and has extra math functions to put it a cut above the rest.
