Mark habits done each day. Track streaks and a simple month heatmap offline.
Daytally is an offline habit check-in notebook. Add the habits you want to mark once a day, check them off as you go, and open a habit to see its streak and month heatmap on this phone.
Mark a habit for today
On the home list, tap the square next to a habit to mark today done. Tap again to clear the mark. Open a habit for more detail, or use Mark today done on the habit screen. Counts at the top show how many habits are done and how many are still open for the day.
Streaks
A streak counts consecutive checked days ending today. Miss a day and the current streak resets to zero. Longest keeps the longest unbroken run recorded for that habit so far. These numbers are notes for you; they do not change anything outside the app.
Month heatmap
Each habit has a calendar grid for the month. Green days are checked. Tap any day in the month to toggle that date. Use Prev and Next to move between months when you need to fix an older mark or look back at a quieter week.
Add and edit
Give each habit a short name and an optional note. Rename or change the note later from Edit. Remove a habit to clear its name, note, and all check-ins from this phone. Other habits stay as they are.
Guide and settings
The Guide explains check-in, streaks, and the heatmap in plain steps. In Settings you can load a small sample list to see how the screens look, or reset everything and start from an empty list.
Daytally stores habit names, notes, and check-in dates only on this phone. There is no account, no cloud sync, and no ads. The app does not use the internet. It is a simple offline tally for habits you want to mark day by day.
