Etar Calendar

Etar (from Arabic: إِيتَار) is an open source material designed calendar made for everyone!



Well, I wanted a simple, material designed and state of the art open source calendar that anyone can make it better.

Special thanks

The application is an enhanced version of AOSP Calendar. Without the help of
Free Software for Android team,
this app would be just a dream. So thanks to them!
