Loop Habit Tracker

Loop Habit Tracker is a habit tracker by Álinson Santos Xavier, with more than five million downloads on Google Play; on your home screen it’s called Habits. You list the things you want to do regularly and mark each day whether you did them. Its README sums up the idea: “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 progress.” It has “no artificial limits”, “There are no in-app purchases”, and “There are no advertisements”.

How it works

• Two kinds of habit: yes-or-no ones (“Did you exercise?”) and measurable ones with a unit and a target of at least or at most a number (“How many pages did you read today?”).
• Frequencies from every day to every few days, weeks or months, or a number of times per week or month. You don’t pick weekdays: the FAQ suggests saying you want to repeat a habit, for example, two times per week.
• A strength score instead of an all-or-nothing streak. The FAQ explains that it uses “a statistical method known as exponential smoothing”: “If you perform a daily habit perfectly, the score reaches 80% after one month, 96% after two months and 99% after three months.”
• A page for each habit with the score over time, an editable history calendar, best streaks and how often you did it.
• You mark a day by pressing and holding; a setting switches this to a single tap. Other options, all off by default, let you mark a day as skipped so it doesn’t break a streak, tell days without data apart from real lapses, and start a new day only at 3 AM.

Reminders and widgets

Each habit can have a reminder at a time and on days you choose; from the notification you can mark it done or snooze it. According to the FAQ, Loop shows a reminder only “if the task has not been already completed that day”. Reminders use Android’s exact alarms: if that permission is taken away on Android 12 or later, the app skips scheduling them. When reminders arrived late on one phone, the developer pointed to the dontkillmyapp.com instructions for the phone’s battery settings: “it’s an Android/Motorola issue.”

Six home-screen widgets show checkmarks, history, score, streaks, frequency and targets. Tasker and similar apps can add checkmarks through a plugin.

Your data

The app asks for no internet permission at all. Its privacy policy: “All data provided to Loop Habit Tracker is only stored locally in your device. Your data is not uploaded anywhere.” An experimental sync feature was removed in version 2.0.1 in 2021 with the note that it would return in 2.1; it hasn’t come back.

• Export full backup saves everything in one file that Loop can import again; Export as CSV creates spreadsheet files, which can’t be imported back. Both are offered through Android’s share menu, not a save dialog; the developer says that is intended.
• Automatic backups: once a day, when you open the habit list, the app saves a copy in its own folder and keeps the five newest. That folder is deleted when you uninstall the app, so copy a backup somewhere else from time to time.
• Import data reads Loop’s own backups and files from Tickmate, HabitBull and Rewire.

About this file

• This is F-Droid’s build of version 2.3.2, from 17 October 2026, signed with F-Droid’s key. The developer’s APKs on GitHub use the developer’s own key, so neither installs over the other; we couldn’t check the signature of the Play version, so don’t count on switching to it by updating either.
• 2.3.2 fixes the styling of the widget picker, lets the habit editor scroll when the keyboard is open, fixes a crash when charts are moved to dates before 1970, improves the touch ripple in dark themes, and handles navigation-bar insets on the settings screen.
• Two closed reports still describe this version’s weekly “At most” behavior. Broken-habit marks can be missing from the calendar and streaks (#2212); a fix landed after 2.3.2 on the development branch. Reminders can behave as if the target were “At least” (#2386), which the developer closed as intended behavior and linked to the project’s frequency design.
• The 10.8 MB file has no native code and needs Android 9 or later. Its 6 permissions cover notifications, exact alarms, restarting reminders after a reboot and vibration. Our scan found no trackers.
• The screenshots are the project’s own, from 2021, older than the streaks for measurable habits that version 2.3.0 added.
• The README licenses Loop under the GPL-3.0 or later. The source of this version is at https://github.com/iSoron/uhabits/tree/v2.3.2.
• “Loop Habit Tracker™ is a trademark of Álinson Santos Xavier”, according to the project’s website. This site isn’t affiliated with the developer.
