10Calc: An adding machine 10-key calculator Android app

10Calc is an adding machine style 10-key calculator Android app for financial and business use cases, particularly accounting. It features a tape journal and supports all the functions of business desktop adding machine calculators, including averages, cost-sell-margin, and tax calculations. What makes 10Calc special compared to other Android calculators is its scrolling tape journal for displaying all operations. The tape can even be shared with others using Android's built-in sharing function, or printed directly to a local printer to keep a hard copy. Another great benefit is its portability: a 10-key calculator is now always ready in your pocket, on your phone or tablet!

Note: 10-key calculators work differently from ordinary consumer calculators, so unless you are familiar with 10-key calculators, this is probably not for you.


Now available for Android phones and tablets, 10Calc behaves similarly to its Windows sibling, but does not yet support item correction. (We will add these and some new functions, based on user feedback.) The initial Android version supports English, with additional languages planned for future releases.


10Calc was originally introduced nearly ten years ago as "10Calc Business Calculator" on the Microsoft Windows Store. It is exceptionally reliable and secure and has received enthusiastic feedback. Make sure to check out the Windows version of 10Calc if you would like a version for that platform.
