Habit Tracker

Build routines by ticking off each habit every day on a simple monthly grid. Add habits such as reading, exercise or drinking water, press a day to mark it done, and see your current streak, best streak and completion rate for the month. Your data stays in this browser, and you can export it as CSV or JSON at any time.

Frequently Asked Questions

How is the current streak counted?

It is the number of consecutive days up to today (or yesterday, if today is not ticked yet) on which the habit was marked done.

Can I tick days in the past?

Yes, any past day can be ticked or unticked. Future days are disabled.

How do I keep my habits when I change computer?

Export to JSON or CSV to keep a record. The tracker cannot import files, so on another device you start a new grid.
