The Habit Tracker is a free, private tool for building and maintaining daily habits. Create custom habits with emoji icons and colors, track them daily with one-click check-ins, visualize your progress with a 28-day calendar heatmap, and monitor your streaks and completion rates — all stored securely in your browser.

Key Features

  • Custom Habits — Create habits with custom names, 20 emoji icons (💪📚🏃💧🧘🎯✍️🚀🎸💊🥗😴🧹💰🌅🎨📱🌿🏋️🧠), and 10 vibrant colors. Edit or delete anytime.
  • Daily Check-In — One-click toggle to mark any habit complete for today. The large checkbox is designed for fast, satisfying interactions.
  • 28-Day Calendar Heatmap — Each habit displays its last 28 days as a colored grid. Completed days are filled with the habit's color. Today is highlighted with a purple outline. Click any past day to toggle it.
  • Streak Tracking — Current streak shows how many consecutive days you've maintained the habit. Best streak shows your longest run ever. These gamify habit building and motivate consistency.
  • Statistics — Total days completed and completion rate (percentage of days completed since you started) give you a clear picture of your consistency over time.
  • localStorage Persistence — All data is saved in your browser's localStorage. It persists across sessions, tabs, and browser restarts. No account needed.
  • Export / Import — Export all habits and history as a JSON file. Import to restore data or transfer between devices.
  • Multiple Habits — Track as many habits as you want simultaneously. Each has its own independent calendar, streak, and statistics.

Habit Building Tips

  • Start Small — Begin with 2-3 habits maximum. Add more only after you've established consistency with the first ones.
  • Don't Break the Chain — The streak counter is your motivation. Seeing a long streak creates powerful psychological incentive to keep going.
  • Stack Habits — Attach new habits to existing routines. "After I brush my teeth, I'll meditate for 5 minutes."
  • Track Early — Check off your habits as soon as you complete them. Don't wait until end of day — you might forget.
  • Allow Misses — Missing one day doesn't erase your progress. Click the calendar day retroactively if you forgot to log.

Frequently Asked Questions

Where is my data stored?

All habit data is stored in your browser's localStorage. It never leaves your device. There are no accounts, no servers, and no tracking. Your data persists across browser sessions but is specific to the browser and device you use.

Can I track past days?

Yes. Click any day in the 28-day calendar to toggle its completion status. This lets you retroactively mark days you forgot to log while they're still visible in the calendar view.

How is the streak calculated?

The current streak counts consecutive days completed going backwards from today. If today is not yet checked, it counts from yesterday. The best streak finds the longest consecutive run across all recorded history.

Can I backup my data?

Yes. Click 'Export' to copy all habit data as JSON to your clipboard. Save it in a text file. To restore, click 'Import' and select the JSON file. This is useful for migrating between devices.

How many habits can I track?

There's no hard limit. You can create as many habits as you want. However, for effectiveness, research suggests focusing on 3-7 key habits at a time for the best results.
