Habit tracker, online and printable

A monthly grid: habits in rows, days in columns. Tick them off in the browser and see how many days of the month worked and how long the current streak is. The same layout prints or saves as a PDF with one button. No account, nothing sent to our server.

How to use it

1. Add one or a few habits, each as a concrete action: "30 minute walk", not "move more".
2. Tick a day when the habit is done. Clicking again removes the mark.
3. The right column shows the month's score and the streak of days in a row. Today without a mark does not break the streak until the day is over.
4. Prefer paper? The print button leaves only the grid on the page, and the print dialog can save it as a PDF.

Where these numbers come from: How long does it take to form a habit? Not 21 days

Common questions

How long does it take to form a habit? Is it 21 days?

There is no evidence for 21 days. In a 2010 study by Lally and colleagues, 96 people took up a new daily behaviour for 12 weeks; it became automatic after a median of 66 days, with a range from 18 to 254. Exercise habits generally took longer than eating and drinking ones, like water with lunch.

Does missing one day ruin it?

In the same study, missing a single day did not materially affect habit formation. Coming back the next day matters more than an unbroken streak, which is why the tracker shows the month's score as well.

How many habits should I track at once?

Research sets no hard limit. In practice it is easier to start with one to three and add more once the first stop taking effort. The tracker holds ten.

Where are my habits saved?

Only in this browser, on this device. Nothing is sent to our server, and clearing browser data removes the grid. An Ordiarion account keeps the history on every device.

How do I get a habit tracker as a PDF?

Press "Print or save as PDF" and pick saving to a PDF file as the printer. The page keeps only the grid for the chosen month with your habits.
