Touch Fin is an RPN financial calculator. This app implements many features of the industry-standard HP-12C.
This app is free and has no limitations whatsoever! Everything works: financial operations, programming, depreciation, statistics... Once installed, it works forever. It is always available and handy for you.
The interface is the cleanest possible: just the calculator filling the whole screen. The app supports three numeric formats: American (999,999.00), European (999.999,00) and Indian (9,99,999.00), and supports copy of the value to the clipboard. Touch the left upper corner of the calculator to open the menu and get access to these features.
If you like this app, consider buying the premium version (Touch Fin Financial Calculator) that is ad-free and loaded with extra features.
