A habit streak is the number of consecutive days you've successfully completed a habit. It's a powerful psychological motivator — the longer your streak, the less likely you are to break it. This technique, popularized by Jerry Seinfeld's "Don't Break the Chain" method, leverages our natural desire for consistency and loss aversion to build lasting habits.

The current streak counts backward from today (or yesterday if you haven't checked in today yet) until it finds a day without a check-in. The longest streak is tracked historically — it's your personal record across all time. Both metrics update automatically whenever you check in.

This tool is designed for daily check-ins on the current day only. You cannot backdate or pre-date check-ins. This encourages genuine daily engagement. If you miss a day, your streak resets — but your longest streak record remains as a testament to your best effort.

Yes! All your habits, check-in history, and streaks are automatically saved to your browser's local storage. They persist across sessions — close the tab, reopen it, and everything is still there. You can also export your data as a JSON file for backup or import it on another device.

Unlike app-based trackers, this tool is entirely web-based with no sign-up, no ads, and no paywalls. It features a GitHub-style contribution heatmap for each habit, giving you a beautiful visual overview of your consistency. The combined overview heatmap shows your total daily activity across all habits. Plus, it works great on mobile — add it to your home screen and use it like a native app.

There's no hard limit — you can track as many habits as you like. However, we recommend focusing on 3-5 key habits for the best results. Too many habits can dilute your focus. Start small, build momentum, and add more as your routines solidify.

• Start small — choose habits that take under 2 minutes initially
• Set a daily reminder — use your phone's alarm at the same time each day
• Pair habits — attach a new habit to an existing routine (habit stacking)
• Don't miss twice — if you slip, get right back on track the next day
• Celebrate milestones — 7 days, 30 days, 100 days are worth acknowledging
