Habit Tracker (local)
100% PrivateProductivity ToolsTrack daily habits on a simple grid, one row per habit and one column per day.
Runs in your browser and saves your work only on this device (browser local storage), never on Ovatly servers. You can export or clear it at any time.
Habits and check marks are saved only in this browser (local storage on this device). Export a JSON backup before clearing browser data.
No habits yet. Add your first habit above, then check off each day you do it.
- 1Type a habit name, for example Walk 30 minutes, and press Add habit.
- 2Tick today's box when you do the habit; use Previous week to fill in days you missed recording.
- 3Watch the streak column: the first number is your current run, the second your best ever.
- 4Export a JSON backup regularly, and import it to restore or move devices.
You tick a reading habit on 30 and 31 January and on 1 and 2 February. On 2 February the tracker shows a current streak of 4, because the run crosses the month boundary without a gap. If you open the tracker on 3 February before reading, the streak still shows 4, because today is not over yet; it only resets when a full day passes unticked.
- Days are your device's local calendar days, so ticks never shift when you travel across time zones; the date follows your device clock.
- Future days are shown but cannot be ticked, and the last 30 days rate counts from the day you created the habit if that is more recent.
- Data lives only in this browser's local storage. Clearing site data deletes it, and it does not sync between devices, so use the JSON export for backups.
At the end of the day after a missed day. If you did the habit yesterday but not yet today, your streak is still alive and counts through yesterday. Miss today entirely and tomorrow it shows 0.
About this tool
The Habit Tracker keeps a simple daily grid for the habits you are building: one row per habit, one box per day, and a tick when you did it. It works out your current streak, your best streak and your completion rate over the last 30 days, all from the days you tick. Everything is stored in your browser on this device, with JSON export and import for backups.
