A habit is something you want to do regularly: reading, walking, practising an instrument, or drinking less. A habit tracker is a record of that, one habit per row and one day per column, so marking a day is one tap and progress becomes visible over time.
Not every habit is daily. Track something every day, three times a week, on selected days, or as a monthly total, and set limits as well as goals.
Named after the German jeden Tag, "every day": habits are built day by day, whatever their schedule.
Habits are built by repetition, not by one decision. Writing each day down makes that repetition visible: a row of marks is easier to keep going than to start over.
Over a few weeks the record also answers what memory cannot — how often you really do the thing, and which weeks it slips.
One tap records a day, and five days sit beside the habit names on a phone — seven with the Compact grid toggle — so keeping the record costs a few seconds.
Your streak follows the schedule you chose rather than a daily one it assumes, a limit you stay under counts as kept, and a day you deliberately skip does not count against it.
Until you sign in, your changes stay only in this browser on this device. When you sign in, you can choose whether to add them to your account. An account keeps your habits in sync on another device.
Either way the record stays yours: what you write down is never analysed or profiled, here or anywhere else, the whole account downloads as one file whenever you want it, and deleting the account deletes the data with it.
Choose every day, every few days from a start date, selected weekdays or days of the month, or a goal such as "3 times per week." Build something up, or keep it under a limit with room for planned exceptions.
Your streak follows the schedule you chose. Today is still open, so leaving it unmarked does not break the streak. You can also skip a day when it should not count.
Track checkmarks or amounts such as liters, pages, or minutes. Set a target or limit for each day, or let everything you record add up across a week or month.
Sign in with an emailed link or code, a passkey, or a Google, GitHub, Apple or Microsoft account where offered, to sync between devices. You choose whether to add your browser-only habits to the account.
Download your habits and history as one file, restore it later, or delete your account yourself. There are no ads and no tracking.
