Great and lightweight. I would appreciate an automatically scaling font size for numbers in calculation, and also option to enable using multiple rows for the calculation. This would enable viewing a long calculation at once, without horizontal scrolling.
★★★★★
Been using it as my main for more than 2 years for basic price calc. Easy and ready to go.
★★★★★
I loved the design of the Google calculator app but I never loved it was made by google and that it collected user data. Opencast is awesome, it looks like google calculator but open source.
★★★★★
Great app EXCEPT it blocks the input of a decimal point before an operator symbol. (edit: only when there is another decimal later in the equation. Try changing 52x0.5 into 52.5x0.5. The program will not accept adding a decimal between 2 and x.) Please change this behavior!!! What we type should be what we get. Just display syntax error if it doesn't make sense. (further edit: also doesn't accept lone operators? Stupid. It shouldn't block any inputs. At least make that a setting plz)
★★★★★
The best! I appreciate the AMOLED dark version, and the clean UI. Thank you guys (much much) keep it up!
★★☆☆☆
Doesn't repeat function when you press equals multiple times, made by someone who has never used an actual calculator, just like Google Calc
★★☆☆☆
Doesn't appear to be able to save numbers into memory.
★★☆☆☆
The calculator can give results in scientific notation, but I don't see any simple way (big E button) to enter values in scientific notation.
★★☆☆☆
Same as built in calc. Cannot see multiple history calculations without covering keypad.
