Habit Tracker Online

Nothing: one miss per seven scheduled days does not break the streak — only two misses in a row do. A study by Lally and colleagues (2010) found that a single missed day does not slow down habit formation. If you skipped for a reason, such as being sick or traveling, mark it as a skip for a reason and the day will not count at all.

Yes. The list shows the last seven days, and any of them can be checked with a tap. Earlier days are in the month view inside the habit’s card. Today never counts as a miss until it is over.

“Print month” prepares a landscape A4 sheet: rows with your habits, the days you already checked, and a few blank rows for new ones. If you have no habits yet, it prints a blank template for the whole month. In the print dialog you can choose “Save as PDF”.

A streak counts days in a row and starts over after a break. Habit strength uses your whole history: each done day nudges it up and each miss nudges it down. After one miss your streak may survive while strength dips slightly; after a long break the streak resets, but strength still reflects the months of consistency.

Choose the “Limit” type and set it, for example “at most 2 cups”. Each tap records one cup, and the day counts if you stayed within the limit. To quit smoking, set the limit to 0 and the tracker shows how many days in a row you have stayed smoke-free.

In the study by Lally and colleagues (2010) the median was 66 days, with a range of 18 to 254 days depending on the person and the habit. That is why the tracker offers 21, 30, 66 and 100-day challenges, and habit strength shows how regular the behavior has already become.

Yes, there is a ready-made “For kids” set: brush teeth morning and evening, make the bed, read a book, put toys away, and do homework on weekdays. The monthly sheet is easy to print and put on the fridge so the child can mark the days.

You pick the days: the week counts as soon as you reach the number of check-ins, and after that the tracker stops reminding you for that week. The streak for such a goal is counted in weeks: it forgives one short week out of four, and two short weeks in a row break it. In the week the habit was created, the goal shrinks in proportion to the days left, and paused days lower it too. Goals like “N times a month” work the same way.

Yes, if you are signed in and have turned on notifications in the calendar settings (⚙): the reminder arrives at the time you chose, even when the site is closed. It comes only if the habit is still unchecked today — not on an unscheduled day, not during a pause, and not once the weekly goal is already met. On iPhone, notifications work after you add the page to your Home Screen (iOS 16.4 or later). Without signing in, habit reminders are not sent.

Before you sign in, your habits and checked days are kept in this browser and are not visible on other devices. When you sign in, they move to your account once, together with amounts, notes and pauses, and from then on the tracker opens on any device. The move only goes into an account with no calendar entries yet: if you already keep a calendar on another device, the old copy from this browser is not mixed into it and does not bring back things you deleted.

No. Even if your calendar is published on your profile, habits do not appear on its public page, in the calendar block on your profile, or in the .ics feed for Google and Apple. Streaks, habit strength and the “3 of 5” summary are shown in the tracker, in your calendar and on your “My progress” page.
