## What is Formules lite?

This is the lite version of the Formulas app. It has limited editing features but allows full use of Formulas documents created with the iOS or macOS versions.

Engineers, scientists, and students often need to perform calculations that are difficult to enter on a calculator. If the calculations involve various formulas, with the need to test various input values, a programming language is appropriate, but source code will never be as intuitive as well-rendered mathematics for designing a formula.
 
With Formulas create beautifully rendered formulas and evaluate them!

You can use real expressions. 

Formulas can be used in other formulas.

On each document, you can define a set of inputs that are used to populate your formulas with values.

The main features are:

-Easily create complex formulas and save them for later use.
-Use as many formulas as necessary.
-Undo/Redo support.
-Change the value of your inputs with immediate results updating.
-Documents created with the iOS version can also be used with the macOS version.
