Habitlog: Habit Tracker Widget

A habit tracker widget on your home screen turns every daily habit into a one-tap check-off, and your year-long streak heatmap fills in, one square a day. Habitlog tracks unlimited habits for free, works offline and needs no account. Both home screen widgets, a Today check-off list and a single-habit heatmap, are free, and you can also check off from the reminder notification.

UNLIMITED HABITS
Unlimited habit tracking stays free, forever, and features that are free today stay free. Every habit type is included:
- Yes/No: read 10 pages, meditate, stretch.
- Count: a goal of 8 glasses of water; tap to add one, long-press to enter the total.
- Measure: 5 km, 2 L, 30 min, with your own unit and daily goal.
- Quit / Limit: habits you want to cut down, such as at most 2 coffees; staying under the limit counts as a success.
Schedule a habit every day, on fixed weekdays, X times a week or every N days. Skip or rest days, when you are ill or travelling, never break the streak. Night owls can start the day at up to 5 am.

SEE YOUR STREAK
A year-long streak heatmap fills in one square at a time for each habit: 53 weeks by 7 days, five shades of green, today outlined and skipped days hatched. Long-press a past day to fill in what you missed, or scroll back to earlier years. An overall heatmap on Today shows how many habits you completed each day. Current and longest streak and 7, 30 and 365-day completion are always visible, and you can share your year heatmap as an image.

CHECK OFF ANYWHERE
The habit tracker widget lists the habits still open today, and one tap on a circle finishes a habit without opening the app. The single-habit heatmap widget shows a full year with a check button for today; both refresh within seconds. Each reminder has Done and Snooze 15 min buttons, so closing a habit takes one tap from the notification.

REMINDERS THAT ARRIVE
Daily habit reminders are scheduled with standard Android alarms and set again after a restart, a time-zone change, a clock change or an app update. If a reminder could not be shown while your phone was off, you get one catch-up notice. The Reminder health screen lists the last 30 reminders with their real delay and tells you when notifications are off or battery use is restricted. Habitlog asks only for the notification permission, when you turn on your first reminder.

SIMPLE BY DESIGN
A minimalist daily habit list: a check circle, the streak number and a small 7-day strip for each habit. No pets, coins, levels or confetti, no sign-in, no to-do lists. One accent color, light and dark themes.

YOUR DATA STAYS HERE
Offline habit data never leaves your phone: no account, no server. Check-offs are included in your own Android backup, you can export and restore a .habitlog backup file at any time, and you can import your history from a Loop Habit Tracker CSV export.
