The calculator has a nice large screen, good to be taken as a key and highlight a control strip on which all computing operations are logged. The functionality is very low (basic arithmetic, percent calculation, memory function, point-on-wave calculation), but for most purposes should the rich, z. B. as Behelfskasse. Entries on the control strip can be change or subsequently provided with additional text, but since I can not print it, I think that rather gimmick. 1 point deduction for appearing on my tablet during initialization slight graphical glitches and that you can delete the entire control strip by pressing the AC-button without the app intercalates a confirmation prompt.
