Formules app for iPhone and iPad

Engineers, scientists and students often have a need to do calculations that are impractical to enter on a calculator. If the calculations involve various formulas, with a need to test for various input values, a programming language is appropriate but source code will never be as intuitive as nicely rendered maths to design a formula.

With Formules, create nicely rendered formulas and evaluate them !

On each document you can define a set of Inputs that are used to feed your formulas with values.

The key features are :

-Easily create complex formulas and save them for later use.
-Use as many formulas as you need.
-Support for Undo/Redo.
-Change the value of your inputs with an immediate update of the results.
-Formulas can depend on other formulas.
-Create Real and Boolean expressions.
-Documents can also be read and modified using the macOS version.
