Loop Habit Tracker review

Loop Habit Tracker is the best free option for Android, and it costs nothing at all: there is no paid tier and the developer does not even accept donations. It is open source under GPLv3 and available on Google Play and F-Droid, where it has more than 5 million downloads. The design choice that matters most for consistency is the habit score. Instead of resetting to zero after one missed day, Loop strengthens a habit with every repetition and weakens it with every miss, so a few missed days after a long run do not erase your progress. Schedules go beyond daily, such as 3 times every week or every other day, and each habit gets its own reminder that you can check off from the notification. Loop works offline with no account, and you can export to CSV or SQLite. The trade-offs are real: there is no iPhone version, no cloud sync and no guidance on which habits to build.
