# Loop Habit Tracker (open-source productivity app)

> Loop Habit Tracker is a free, open-source productivity app for Android. Track your habits and long-term goals. It has 10,307 GitHub stars and is released under the GPL-3.0-only license, and you can install it from F-Droid and Google Play.

Loop is a simple app that helps you create and maintain good habits, allowing you to achieve your long-term goals. Detailed graphs and statistics show you how your habits improved over time. Features * Simple, beautiful and modern interface: Loop has a minimalistic interface that is easy to use and follows the material design guidelines. * Habit score: In addition to showing your current streak, Loop has an advanced algorithm for calculating the strength of your habits. Every repetition makes your habit stronger, and every missed day makes it weaker. A few missed days after a long streak, however, will not completely destroy your entire progress.
