Take notes, plan tasks, track habits

OpenHabitTracker is free and open source. The app has no ads, no trackers, no account, no subscriptions and no in-app purchases.

• All your data stays on your device, and syncs only to a server you run yourself
• Available on Windows, Linux, Android, iOS, macOS, as a web app, and self-hosted
• Localized to English, German, Spanish, Slovenian, French, Portuguese, Italian, Japanese, Chinese, Korean, Dutch, Danish, Norwegian, Swedish, Finnish, Polish, Czech, Slovak, Croatian, Serbian

Key features:

• Markdown notes, rendered in the list so reading one costs no clicks
• Tasks with a planned date and time, a duration, a checklist and a timer
• Habits measured by how overdue they are rather than by an unbroken streak: a habit with a 10 day interval that is 2 days overdue reads 120%
• Categories and priorities across notes, tasks and habits
• Import and export JSON, YAML, TSV and Markdown, plus import from a Google Keep Takeout ZIP
• 26 themes with dark and light mode
• Full keyboard navigation and screen reader support

Search, filter and sort:

• Control what the list shows with search, date, category, priority, status and sort
• Planned dates and done dates filtered separately, each before, on, after or not on a date you pick
• Date filters take a fixed date or a number of days from today, worked out when the query runs, so a saved filter never goes stale
• Filter habits by how overdue they are, with a lower bound, an upper bound, or both
• Turn the done-date filter around to see what you have not done in a period
• Eleven sort keys, chosen separately for notes, tasks and habits
• Search reads note text and checklist items, not only titles

Customization:

• Almost everything on screen can be turned on or off: which page and which sidebar open at start, what each row shows, which calendars appear, how the filters are drawn, and how tightly the lists are packed
• Some of them add or remove whole blocks from a habit, so the same habit is either a short form or a full statistics page
• A background color to tell your notes, tasks and habits apart at a glance
• Settings are saved, synced, and included in JSON and YAML backups

The default port is 5050. You can change it to 80 to avoid typing the port in the address, or to any other free port if 5050 is already in use - update the port in docker-compose.yml accordingly.

After you login at http://localhost:5050/login you can use the same browser tab to access:

• logs: http://localhost:5050/watchdog
• OpenAPI json: http://localhost:5050/openapi/v1.json
• OpenAPI UI: http://localhost:5050/scalar/v1
