The hardest part of building a habit is seeing whether you are actually doing it. The ChrysoKit Habit Tracker gives you a 28-day heatmap that makes consistency obvious at a glance.
Why use it
Most habit apps are subscription-based and store your data on someone else's server. Ours is free, local and private. Your habits never leave your browser.
How to use the Habit Tracker
- Add habits with a name and an optional description.
- Tap each day to mark it complete.
- Watch the 28-day heatmap fill in.
- Export your log as JSON if you want to back it up.
Features worth knowing

All data lives in your browser. Nothing is sent anywhere.

Pro tips
- Pick small, daily habits. 'Read for 10 minutes' is more sustainable than 'read a chapter every day'.
- Two or three habits is plenty to start. Adding more usually means dropping some within a month.
- Export your log weekly. Browser data can be cleared by accident; a backup costs nothing.
Privacy first. The Habit Tracker runs entirely in your browser. Nothing you enter is sent to a server.
Open the Habit Tracker each morning. The streaks you can see are the streaks you keep going.
