There are many calculators for Android, but this one is definitely one of the good. Simple, but well-crafted user interface and quite a large range of functions. Criticized the of my Vorrezensenten "error" 5-5 = 0, I see as an input error of the user - to write just is not two stroke invoice operators in direct succession - and if you use parentheses, everything works as desired. In my view, quite recommended if you are looking for a more powerful replacement for the minimalist Android standard calculator.
