ProCalc

Simple multiplications can be performed by each mathematical calculator. However, even just simple examples as the Pythagorean Theorem require a clearly arranged user interface.

Especially such demanding operations are in the focus of the ProCalc app. Mathematical and scientific operations are entered like they are used on written paper. Exponents, roots and fractions are displayed clearly arranged and plain without losing the overview about the entire formula. Complicated or confusing parentheses became obsolete.

The key layout is made flexible for any arrangements and it can be set according individual preferences. Even color schemes can be freely selected.

A history menu shows past or recent calculations and they can be simply restored for current operations.
