Rangeen Calculator

A powerful Rangeen Calculator with a simple interface.

Rangeen Calculator is a simple 4 function calculator, with a panel that has more advanced functions when you need them. It includes history, real time graphing, base Rangeen Calculator, and more. It also comes with a lockscreen widget, a floating Rangeen Calculator, and a wear app so you can use whichever is most convenient.

The goal is a simple and uncluttered Rangeen Calculator.

Because Rangeen Calculator is a full replacement for your stock calculator, we recommend you disable the one that came with your phone. If you long press your original calculator, and drag it to App Info, you can Disable it where you'd normally find Uninstall.
