The habit tracker you actually own.
Habit apps rent you your own streaks — an account, a cloud, $80 a year. Habitline is a file on your computer. Open it, track your habits, close it. Pay $5 once. It works offline, forever, and your data never leaves your device.
No account · no subscription · no tracking
This is the real app, running in this page. Click the circles.
The subscription math nobody shows you
A typical habit app charges ~$6.99 a month for a checklist. Each slab over there is one month you pay again for the same feature: a circle you tap. Keep the habit five years and the checklist costs more than a weekend trip.
Habitline is 1.2% of that. Once.
$6.99 × 60 months = $419.40. We rounded down.

Small app. Serious tracking.
Streaks that respect real life
Not everything is daily. Set "Gym, 3× a week" and hitting three keeps the streak alive — no broken chains for living like a human.
Gym — 2 of 3 this week, streak safe
A year at a glance
Every habit gets a full-year heatmap — sparse where you started, dense where it stuck. The good weeks look good, the gaps tell the truth, and both are yours to keep.
52 weeks × 7 days · one habit, one file
Your data is a file, not a hostage
One click exports everything as clean JSON. Import it on a new machine and carry on. No sync service to shut down on you.

Instant, because it's local
No spinner, no sync conflicts, no "reconnecting…". The database lives in your browser — taps land in under a frame.
Your data never leaves your device.
That zero is the number of network requests Habitline makes. There is no server — everything lives in your browser's local database (IndexedDB), on your machine. Export it as clean JSON any time.
Questions, answered straight
What exactly do I get?
A small zip file. Unzip it, open index.html in any modern browser, and the full tracker runs — daily and weekly habits, streaks, heatmap history, backups. A plain-English README and license are included.
Where does my data live?
In your browser's local database (IndexedDB) on your own device. Nothing is uploaded anywhere — there is no server. Export everything as JSON any time; import it on another machine.
Does it work on phones?
Yes — it runs in any modern mobile browser. It's happiest on the computer where the file lives; use Export/Import to move between devices.
Is there really no subscription?
Really. $5 once. The app is a file you own — it cannot expire, lock you out, or start charging monthly.
What about refunds?
If it isn't for you, email us within 14 days of purchase and we'll refund you.
Own your habits. Literally.
$5 once.
One payment, one file, every streak yours forever — the last habit-tracker payment you'll ever make.
