Abacus is a simple yet powerful calculation tool. It is easy to use and not difficult to master.
Our app, Abacus – Natural Feel, is designed to stay true to the original — simple and easy.
We do not believe in extra features or gimmicks. We focus mainly on usability.
As a result Abacus – Natural Feel does feel like actual abacus on which you can flick and perform smooth and frictionless calculation.
Abacus with natural "flicking" feel.
