Droid-Break

Droid-Break is a list of free and open source Android apps inspired by Prism-Break. Our purpose is to show you high quality alternatives to the big proprietary solutions.
Please note that open source apps don't guarantee absolute freedom, e.g., an open source Twitter client still sends everything to Twitter's servers.
Anyway, we believe it's the best we can come up with and that in many cases it's the better choice.
If you think an app should be added please write an email, a tweet, a Disqus comment, or fork the project on GitHub and make a pull request.

You will find most of these apps in the F-Droid repository. Also, you might want to consider flashing a custom ROM like CyanogenMod or Replicant on your device.
