Loop Habit Tracker review

Loop Habit Tracker, by Álinson S. Xavier, is free and open source under GPLv3, available on Google Play and F-Droid, with 5M+ downloads on Google Play. Its main idea is a habit score next to the streak: the app uses exponential smoothing, so each repetition strengthens the habit and a few missed days after a long run do not reset you to zero. The FAQ says a perfectly kept daily habit reaches 80 percent after one month, 96 percent after two and 99 percent after three. Schedules are flexible: you set how many times per period, such as 2 times per week, and the app fills in the rest. Each habit gets one reminder you can check, dismiss or snooze from the notification. There are no ads or online accounts, and data never leaves the phone unless you export it to CSV or SQLite. The trade-offs are an Android-only app, no sync, and no bad-habit tracking; the FAQ suggests rephrasing, such as a smoke-free day.
