Top opensource Android apps

Since my transition to Linux 🐧 I have acquired a culture of open source software, a culture that is expanding with every day I spend in Linux.

Especially after having seen the importance of open source applications in fighting the monopoly of Big softwares companies such as Microsoft, Apple, Adobe ...

It has expanded to include even the way I use my smartphone, where I have become inclined to use open source applications, because of my love for open source on the one hand, and on the other hand because of the thirst of commercial software to spy on my personal information as well as the aggressive bad ads that hinder the good use of softwares.

Today, after a modest search I am delighted to present you some of the most important open source Android applications.
