Loop Habit Tracker is a free, open-source Android app for building and maintaining habits, created and maintained by developer Alinson Santos Xavier under the GPLv3 license. Users create habits with flexible schedules (daily, specific weekdays, or a target number of times per week or month) and check them off as completed, with the app generating streak counts, completion scores, and detailed charts and statistics.
Because the source code is publicly available on GitHub, the app has no ads, no account requirement, and no data collection; all habit data is stored locally on the device and never transmitted anywhere. It supports home screen widgets for quick habit logging, customizable reminders, and CSV/database export and backup of habit history.
Loop Habit Tracker is aimed at privacy-conscious Android users and open-source enthusiasts who want a lightweight, offline habit tracker without subscriptions or cloud accounts. It is distributed for free via Google Play and F-Droid, with no in-app purchases or premium tier.
