About this app

This supercalculator contains within itself the complete functionality of today's high-end calculators. No feature was left behind during development. Featuring an automatically re-sizing, navigable screen with unlimited digit support.

Its unique design allows you to comfortably write complicated equations, while also enabling you to compose short and simple calculations fast. You can have a result bank of up to 1000 calculations of which you can always go back and edit.

Unparalleled in features, its one-screen functionality makes it one of the simplest yet powerful calculators you will ever have the pleasure of operating.
