About this app

Habit tracker with 4 free home screen widgets. Check one off without opening the app.
Works offline. No account, no ads.
The calendar, the year grid and CSV import are free too.

For a morning routine, workouts, meditation, reading, water, study or journaling — or for quitting something.

4 WIDGETS, ALL FREE
Today: your list, on the home screen. Tap a row to check a habit off, or to add one more of whatever you're counting. The app never opens.
Streak: your longest active streak, which habit it belongs to, this week's dots, and that habit's record.
Progress: how much of today is done.
Heatmap: 20 weeks of one habit you pick, filling in square by square.
Every widget has its own transparency slider, so it sits on your wallpaper instead of on top of it.

YOUR MONTH, AND YOUR YEAR
The calendar shows a whole month at once — the runs, the gaps, the day you came back — and the day you tap opens underneath it, so nothing covers the grid. Forgot to log yesterday? Tap any past day and fill it in.
Every habit also gets stats at three zoom levels: month, quarter, and a 365-day grid you can watch fill in. Tap a month to drill in. All free.

NOT EVERY HABIT IS A CHECKBOX
Do it: read, stretch, call your mom.
Avoid it: an avoid habit counts your days clean instead of your check-ins.
Measure it: 8 glasses, 20 pages, 30 minutes. Name your own unit, and add to it from home, the calendar or a widget.
Every day, chosen weekdays, or 4 times a week. 54 ready-made templates if you'd rather not start from blank.

REMINDERS
Give each habit its own time. The wording changes with how long your streak is and what hour it is, and every reminder carries a Done button — a habit can be finished from the notification shade. There's an optional evening nudge, at an hour you pick, for anything still unchecked, louder when a streak of 3 days or more is about to break. Reminders survive a reboot.

MAKE THE LIST YOURS
3 home layouts (simple list, weekly 7-day strip, grid cards), 166 icons, 12 categories, 8 habit colours, 9 sort orders, long-press to drag them into order, and grouping by time of day or category. Three animated backgrounds — two dark, one light — all free. Archive a habit when you're done with it and its history stays.

ALREADY TRACKING SOMEWHERE ELSE
Switching shouldn't cost you your history. Prisma reads the export from Loop Habit Tracker, HabitKit, Habitify and HabitBull, or any plain CSV, and works out the format and the date order on its own. Export back to CSV whenever you want. Both directions are free.

NO ACCOUNT. NO SIGN-UP. NO ADS.
A habit tracker shouldn't need your email. Open it and start. Your habits live in a database on your phone, and we never upload them to our servers. Checking off, reminders, widgets and the calendar all work offline. Android's own backup can copy them to your personal Google Drive so they survive a new phone — your Google account, not ours, and you can switch it off. Prisma also keeps rotating local backups and snapshots your data before restoring one, so restoring the wrong file costs nothing. One button erases everything, for good.
It sends usage, performance and crash data to Firebase and a purchase identifier to RevenueCat, tied to a random install ID. Never your habit names.

WHAT'S FREE
5 habits, with all of the above: the 4 widgets, the calendar, the 365-day grid, streaks, reminders, CSV import and export, automatic backups, light and dark, and 7 languages (English, Spanish, Portuguese (Brazil), German, French, Japanese, Korean) with an in-app switcher.

WHAT PRISMA PRO ADDS
Unlimited habits, a Strength curve of your score over time, your best and worst weekdays, target progress, and a streak ledger with your longest runs and the dates you set them. Plus 50 gradient habit colours. Monthly and yearly are subscriptions. Lifetime is a single payment, not a subscription. If a free trial is available on your Google account, Play shows the terms before you confirm.

Start with one habit. Check in tonight.

What’s new

The parts you touch every day got a pass.

• Backgrounds are back — Classic, Eclipse and Slate, plus light mode
• A new habit takes four steps instead of nine, and picks its own icon
• The calendar keeps your day under the month, so more habits fit
• Widgets: numbers that add up, your habit colours, and your language
• Korean joins, for seven languages in total
• Fixed: taps that didn't show, and CSV imports reading dates in the wrong order
