For those of you who don't know, FOSS stands for Free and Open-Source Software. In Layman's terms, the principle of FOSS allows anyone to run a specific program for any purpose, but it also gives them open access to the code, allowing them to view, change or modify the piece of software behind the scenes. Users are free to contribute and re-distribute FOSS software. It encourages freedom and community contribution, as opposed to closed-source software, which is created by a company for profit and doesn't allow you to see behind the scenes.


FOSS isn't just about desktop software, though, this extends to mobile applications. Today, I'm going to go through some of my favorite apps from F-Droid.


1) Loop Habit Tracker

Loop Habit Tracker is a free application that helps you track your daily routine.


Key Features

  • Reminders
  • Habit score: In addition to showing you your current progress path, Loop has an advanced algorithm so as to calculate the strength of your habits. Every successful completion of one of your recurring tasks makes your habit stronger, and every missed day makes it weaker.
  • Graphics & Statistics of your calculated progress.

2) Blokada

No more using dedicated "ad-block browsers." Blokada is an open-source application that blocks ads for any app on your device universally. Blokada says: "You should be careful when using any apps that filter your traffic since they can steal your sensitive information. Blokada is open-source, which means anyone can see its source code to be certain that it's safe to use. Put your trust in a thriving community that believes an ad-free world is better!"


3) Scarlet Notes

Scarlet is an advanced note-taking application similar to Google Keep, but on steroids.

4) Raise To Answer

This app needs no further explanation. Raise the phone to your ear to automatically answer calls instead of having to swipe or click "Answer" to activate a phone call.
