Calcoliner, the classic desktop calculator revisited, with a lot more!

Core strength of the App is the virtual 'paper tape', realistic and feature rich.
Calcoliner uses it to display each calculation and comment in a very intuitive and practical manner.

The roll can be scrolled and expanded at your convenience to allow for a comfortable view of the calculations.

Automatic saving of data allows for keeping in a permanent way all calculations in progress for further reviewing and completion.

Textual comments can be added to every operation. It comes very handy where you need to manage a number of variable expenses and you don't want to miss anything. An ideal feature for expense reporting!

Calculations can then be selected and sent via email or even printed via AirPrint.
Every single figure printed on the roll can be retrieved and sent back to the display to be used again for new calculations.

Calcoliner offers two different switchable ‘calculation modes’:

DIRECT MODE: every operation is evaluated as it is entered.
EXPRESSION MODE: every operation is evaluated according to arithmetic precedence.

In Direct Mode % and Delta % operations are possible whereas in Expression Mode mathematical notation with parenthesis is fully supported.

The ability to let group of calculation performed in the two above modes to co-exist in the same ‘paper roll’ is an exclusive feature of Calcoliner.
Operators use different colors to highlight actual mode in use.

Other features: Memory store and recall; Computation can be processed with truncation of decimal figures and rounding.

Language localization available in English, German, Italian, Chinese, Russian and Spanish.

Ratings and Reviews



Would give five stars if the following two things were possible: 1. the ability to change figure entries by line instead having to redo whole grid if mistake is made during input (this can be done with text entries) and 2. Would be smoother if text were to the left of figures.

No Landscape orientation


This application does not operate in horizontal mode on IPad. Unknown as to why, since e-mail to support is ignored. I therefore assume that there is no product support. It does what I wanted, but have no idea why it only operates in vertical mode. Also, when developers refuse to respond to request for support, I am personally offended because I paid for this. If it were free I wouldn't expect as much.

Buttons are too small


Functional and does the job but buttons are too small and there is no landscape orientation to make them bigger. I do like the sounds and the tape that shows your previous entries.
