F-Droid is a software catalog for Android devices that consists specifically of Free and Open Source Software (FOSS). According to the Free Software Foundation, a program is considered free software if the program's users have the four essential freedoms:
(0) The freedom to run the program as you wish, for any purpose.
(1) The freedom to study how the program works, and change it so it does your computing as you wish. Access to the source code is a precondition for this.
(2) The freedom to redistribute copies so you can help your neighbor.
(3) The freedom to distribute copies of your modified versions to others. By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this."
