Habit Tracker

What this tool does

Habit Tracker lets you add any number of habits and mark each day done or not done on a 35-day grid, automatically calculating your current consecutive-day streak, saved locally to your browser with no account needed.

Building a new habit is easier when progress is visible, a growing streak of consecutive done days provides real motivation, but tracking it in a notebook or spreadsheet is more friction than a quick daily check deserves.

This tracker lets you add any habit and mark each of the last 35 days done or not with a single click, automatically calculating your current consecutive-day streak, saved locally with no account required.

How to use Habit Tracker

1. Add a habit by name.
2. Click a day’s square to mark it done (click again to undo).
3. Watch your streak count update as you mark consecutive days.
4. Add more habits as needed, each tracked independently.

Tips for better results

• The streak counts consecutive days up to and including today, missing even a single day resets it to zero, which is exactly the real-world mechanic that makes a visible streak motivating.
• You can mark a past day retroactively if you forgot to check in, the grid covers the last 35 days, not just today.
• Track only a few habits at once rather than many, spreading attention across too many new habits simultaneously tends to reduce consistency on each individual one.
• Your habits and history are saved to this specific browser’s local storage, they won’t appear if you check in from a different device, keep that in mind if you switch devices often.

Common use cases

• Building and maintaining a daily habit (exercise, reading, meditation) with visible progress.
• Tracking several independent habits side by side to see which ones stick.
• Motivating consistency through a visible streak counter rather than relying on memory alone.
• Reviewing the last month’s worth of a habit’s consistency at a glance via the grid.

Common mistakes to avoid

• Tracking too many habits simultaneously, spreading focus thin and typically reducing consistency across all of them rather than building any single one reliably.
• Forgetting that local storage is tied to one specific browser and device, if you check in from your phone one day and your laptop the next, your streak data won’t be consistent between them.
• Breaking a long streak and getting discouraged rather than simply restarting, a reset streak counter reflects the mechanic accurately, but a single missed day doesn’t erase the actual progress and habit-forming value of the days before it.
