How we grade them
| 3.0GPALoop Habit TrackerVery good | 3.6GPAOpenHabitTrackerExcellent | |
|---|---|---|
| Value for money | AIt's free. The complete app comes from Google Play or F-Droid under the GPLv3 licence, with no ads and no in-app purchases. There's nothing to weigh up, because there's nothing to buy. | AIt's free. All of it, on every platform. The maker says there are no ads, no trackers, no subscriptions and no in-app purchases, so there's no paid plan to weigh up. |
| Free plan and trial | AEverything is free: unlimited habits and every feature, with no ads, no in-app purchases and no account. You can't do better than that. | AEverything is free with no account, on web, Windows, Linux, Android, iOS and macOS. Even the sync server is free, under the GPL-3.0 license. You just have to run it yourself. |
| Features | BA strength score for each habit, schedules like 3 times per week or every other day, skips that leave the score and streak alone, reminders you can answer from the notification, widgets, graphs, and export to CSV or SQLite. But there's no built-in sync, and only positive habits are tracked. | AHabits are counted in repetitions, time spent or a quantity, each with a timer, a checklist and a calendar. Charts show history, weekday frequency and your ten longest streaks. Tasks and Markdown notes sit alongside, with eleven sort keys. |
| Ease of use | BWe have no App Store rating on record for it, as it's an Android app, so a B is as high as we go. It works offline without an account, and a habit can be checked off straight from its reminder. | BNo rating on record, so a B is our ceiling. There's no account, so you install it and start. Sync is the hard bit: that's a Docker server you host, and the web app keeps its data on the one device. |
| Platforms and integrations | DAndroid only. The FAQ says there is no iOS version, and that App Store apps using the name are unauthorized copies. Version 2.3.1 on F-Droid needs Android 9.0 or newer. Tasker can add checkmarks, and that's the one hook to other apps. | BWeb, Windows, Linux, Android, iOS and macOS, so every device is covered. But the only thing it connects to is a Google Keep import, and no API is listed. Data goes in and out as JSON, YAML, TSV and Markdown. |

Who each one suits

- Anyone who wants to export habit data to CSV or SQLite
OpenHabitTracker
- People who want notes, tasks and habits in one free app

- Using the same tracker on Windows, Linux, macOS and phones
Worth knowing
Loop Habit Tracker
- Android only: the FAQ says there is no iOS version and that App Store apps using the name are unauthorized copies.
- There is no account or built-in sync; backups rely on Android's backup service or a manually exported file.
- Only positive habits are tracked, so a habit to quit has to be rephrased, for example as a smoke-free day.
- Version 2.3.1 on F-Droid requires Android 9.0 or newer.
OpenHabitTracker
- Syncing devices needs a Docker server that you host yourself. The vendor's own web app saves data on the device and has no online sync.
- The Docker image is described as a server app for one user.
- On Linux and in the web app, notifications arrive only while the app is open.
- It is a personal project by a single developer, with feedback handled on Reddit and GitHub.
Key features
Loop Habit Tracker
- Habit score
- A formula based on exponential smoothing rates the strength of each habit. Every repetition raises the score, and a missed day lowers it without resetting progress.
- Flexible schedules
- Besides daily habits, schedules such as 3 times per week or every other day are supported. A day can be marked as skipped, which leaves the score and streak unchanged.
- Reminders
- Each habit can have its own reminder at a chosen time of day, and a habit can be checked or dismissed directly from the notification.
- Home screen widgets
- Widgets for checkmarks, frequency, habit strength, history and streaks let you track habits from the home screen without opening the app.
- Graphs and statistics
- Graphs show how each habit has developed over time, and the full history of a habit can be scrolled back through.
- Data export and Tasker support
- Data can be exported to CSV spreadsheets or an SQLite database file, and other apps such as Tasker can add checkmarks.
OpenHabitTracker
- Overdue ratio instead of streaks
- The time since a habit was last done is compared with its repeat interval: a 10-day habit that is 2 days overdue reads 120%. Classic streaks can be switched on.
- Flexible habit rules
- A habit sets how many times and how often per day, week, month or year, and is measured in repetitions, time spent or a quantity. Each has a timer, checklist and calendar.
- Notes and tasks alongside habits
- Markdown notes are rendered in the list, and tasks carry a planned date and time, a duration, a checklist and a timer. Categories and priorities apply to all three.
- Search, filter and sort
- Lists can be narrowed by text, date, category, priority and status, habits can be filtered by how overdue they are, and there are eleven sort keys.
- Statistics and charts
- Weekly statistics sit beside each list, and every habit has charts for progress toward its target, history by day to year, its ten longest streaks and weekday frequency.
- Self-hosted sync and file formats
- Devices sync through a Docker image run on your own server. Data imports and exports as JSON, YAML, TSV and Markdown, and Google Keep notes can be imported.
