Very nice calculator for your Fitbit. Colors configurable through a settings option page. Works like a standard Japanese pocket calculator showing direct intermediate results (simple). You will love it! Tapping the result display serves as backspace key. Or use the right buttons for backspace.

Install and use for free if you already purchased our Blowout Sale bundle offer!

Otherwise this is a paid app. You will need (before you can use this great calculator app) to purchase a (lifetime) license for just $1.99 ex tax. It’s a bargain. But consider to purchase the bundle offer and you will never have to pay for our clockfaces and apps EVER! Now that is a real bargain!
