Habit Tracker
Track daily habits online with streaks, completion rate, and private browser storage.
Most habits fail when tracking is too heavy to keep up with. This habit tracker gives you a simple weekly or monthly grid, instant streaks, and a clear completion rate without requiring an account. Add your routines, mark each day, and keep the data in your browser. When you want long-term planning, save the tracker to 12wk.app and connect habits to weekly reviews.

How to use the habit tracker
Add each routine you want to build, then choose a weekly or monthly view. Tap a cell to mark a day done and the grid instantly recalculates your completion rate and current streak. Switch between week and month to see short-term consistency or the bigger pattern over time. Everything is saved in your browser, so you can close the tab and return later without losing data or creating an account, and nothing is shared until you choose to sign in.
What to track and common mistakes
Good starter routines are small and daily: a ten-minute walk, one page of reading, or planning tomorrow before bed. The most common mistake is loading up too many routines at once, which makes a single missed day feel like failure. Start with three, keep them visible, and add more only once a streak feels automatic. A second mistake is tracking vague habits like "be healthier" — pick a concrete action you can mark done or not done. Finally, avoid all-or-nothing thinking: a partial week still beats an empty one, and the grid is there to show progress, not to punish a slip.
Why use this habit tracker?
A lightweight tracker removes the friction from daily follow-through. You can see consistency at a glance, spot missed days early, and decide which routines deserve a place in your next 12-week plan. Because progress is visible, small wins compound into momentum instead of disappearing. Over a few weeks the pattern itself becomes useful feedback: you learn which days are hardest and can adjust the routine before it breaks.
Frequently asked questions
What is a habit tracker?
It is a simple daily log that shows whether you completed a routine on each day. This version stores the grid privately in your browser, so you can start in seconds without signing in or installing anything.
How do I track daily habits online?
Add each habit, choose week or month view, and mark the days you completed it. The tool then calculates completion rate and best streak automatically as you go.
Is this habit tracker free?
Yes. The core tracker is free and works without login. Registration is only needed when you want cross-device sync and deeper weekly review features.
What habits should I track first?
Start with routines that support a larger goal, such as sleep, exercise, planning, reading, or focused work. Three to five habits are easier to maintain than a long list.
How many habits should I track at once?
Three to five is the sweet spot for most people. Fewer habits mean each one gets real attention, and a high completion rate keeps motivation high while the routine settles in.
Does the habit tracker work on mobile?
Yes. The grid is responsive and works in any mobile browser, and because data lives in local storage it stays private to that device until you sign in to sync.
How is the completion rate calculated?
Completion rate is the number of days you marked done divided by the days in the selected week or month. It updates the moment you tap a cell, so progress is always current.
