Version: 1.2
Added: 21-12-2016
Updated: 17-01-2017

Application that solves math expressions. Main features:

  • Supports variables (e.g. you can do "a=5", then "a+1" and you get 6)
  • Built-in basic function (like logarithms and trigonometry)
  • Custom functions can be defined (e.g. "log(x,b)=log(x)/log(b)", then log(32,2) will print 5)
  • Variables and functions can be edited both from the prompt and dialogs
  • Can print parsing and evaluation steps.
  • (Android 6.0+ only) can evaluate expressions from text selection in any application (ACTION_PROCESS_TEXT intent).
  • Fully localizable - actually includes English and Italian, you can contribute yor translation with a pull request on GitHub.


  • 1.2: updated build tools to fix crash on some Android versions.
  • 1.1: added localization support and Italian translation; added ACTION_PROCESS_TEXT intent filter.
  • 1.0: Initial version.
