How do I tick off a habit, including for past days?

Press "Add habit" to create one, then press the circle under today's date in the Week view to mark it done; press it again to undo. You can fill in earlier days the same way using "Previous week", or in the Month view. Days in the future cannot be ticked. A circle shows a tick and the habit's colour once it is done.

How are streaks and completion percentages worked out?

The current streak is the number of days in a row ending today, or ending yesterday while today is still open, so it does not drop to zero before you have had a chance to tick. The best streak is the longest run ever. For habits with a goal under 7 days a week, "Weeks in a row on target" counts consecutive weeks that reached the goal. The "Last 30 days" figure compares your check-ins with the goal over the days the habit has existed (at most 30) and never goes above 100%.

What do the Week, Month and Year views show?

"Week" shows seven days per habit with the progress towards each weekly goal. "Month" shows every day of the month for all habits with a total per habit, and you can move between months. "Year" shows a calendar heatmap of the last 53 weeks, either for all habits together (darker means more of them done that day) or for one habit. Under "Week starts on" you can choose Monday, Sunday or Saturday.

Where is my data saved, and can I back it up?

Habits and check-ins are saved automatically in this browser's local storage, so they are there next time on the same device and browser. They are not uploaded and not shared between devices. Clearing site data or using a private window loses them. Use "Download JSON" for a full backup or "Download CSV" for a spreadsheet, and "Import JSON or CSV" to add a file back in. Importing merges habits with the same name and ignores dates in the future. You can have up to 30 habits.

Does it send reminders?

No. The "Reminder note" is text only: it is shown under the habit and in the "Still to do today" list so you remember the cue, such as "after brushing my teeth". The page does not ask for notification permission and does not run in the background, so open it to see what is left for today.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install.

How It Works

The page keeps your habits and the list of days you did each one in this browser, works out streaks and percentages from those dates, and draws the week grid, month grid and heatmap from them.

1
Add your habits
Press "Add habit", then choose a name, an emoji, a colour, how many days a week you are aiming for and an optional reminder note.
2
Tick them off
Press the circle for today in the "Week" view, or go back to earlier days. The "Today" box shows what is left.
3
Watch the pattern
Switch to "Month" or "Year" and read the streaks, the last-30-days percentage and the heatmap.
4
Back up
Press "Download JSON" or "Download CSV" to keep a copy, and "Import JSON or CSV" to bring one back.

Your habits stay in this browser. Nothing is uploaded or put in the page address, and clearing your site data removes them.
