Astrophysics In Action

About Astrophysics In Action Android App

This application is free and ad-based. There is an ad free app.

It's a consolidation of astrophysics formulae and get them into action through forms for calculation.
This way the formulae are given some action and some life.
Some topics in Astrophysics has its group of formulae , of course; therefore, each is accompanied with some information about it by clicking the menu button.

Please ask us for features that you think as an astrophysicist require to be added to this application.


Please notice since this is a free application, criticize it constructively since in the end the application is made for you. However, the newer formulae you ask us asked to add them, they will go into the paid version.

Please write the review in either English or Arabic. The computer translation is weak.

The app also has also an activity to count the stars .
