Habit Tracker
Tappable 7-day grid per habit, current & best streaks, 30-day completion bars & a daily scoreboard — all saved locally.
💡 Streaks count consecutive days ending today (or yesterday, if today isn't marked yet) — so an unbroken run stays alive until midnight. History lives only in your browser.
🔥Streaks you can see — and repair
Each habit gets a 7-day grid you can tap for any day — forgot to mark yesterday? Fix it — plus a current streak 🔥, your best streak 🏆, and a 30-day completion barthat turns green above 80%. A daily scoreboard shows how many habits you've closed today. No account, no app: the whole history lives in your browser.
📊Everything you'd want to know
- Tap any of the last 7 days per habit — late marking keeps honest streaks alive.
- Current streak counts consecutive days ending today (or yesterday if today isn't marked yet).
- Best-ever streak preserved forever — beat your own record.
- 30-day completion rate with a colour-coded bar: green 80%+, amber 50%+, red below.
- Delete asks for confirmation, because a year of history deserves a second thought.
💡The science of streaks
- Habits form through repetition tied to a cue — track the behaviour right after its trigger ('after dinner: revise one chapter').
- Never miss twice: one gap barely dents a habit, two starts a new normal. The grid makes a single miss visible before it becomes two.
- Keep habits atomic — '10 minutes of physics' beats 'study more' because you can honestly tick it.
- 3–5 habits maximum: every habit you add taxes the ones you already have.
💡 Frequently Asked Questions
How does the streak counting work?+
The current streak counts consecutive marked days ending today — or ending yesterday if you haven't marked today yet, so your run isn't broken while the day is still in progress. The best streak is your longest run ever.
Can I mark a day I forgot?+
Yes — the grid shows the last 7 days and every circle is tappable. If you did the habit but forgot to log it, fix it honestly; the streak math updates instantly.
How many habits should I track at once?+
Three to five. Each additional habit costs willpower that the existing ones need. Start with one keystone habit (daily revision is the classic) and add more only after it feels automatic.
Is my habit history private?+
Entirely — it's stored in your browser's local storage on your device, never uploaded. Clearing site data erases it, so avoid doing that if your streaks matter to you.
What completion rate counts as success?+
80%+ over 30 days (the green bar) builds habits reliably — perfection isn't required. Below 50% usually means the habit is too big; shrink it until ticking it daily feels easy.
