Free habit tracker with forgiving streaks

Track a few daily habits week by week, with streaks that forgive a missed day. Private, no sign-up, and you can export your data as CSV or a Thendoo template.

Add your first habit above. Keep it tiny.

Nothing is saved or sent anywhere. Export before you close the page.

How to use it

  1. Add a habit. Keep the name short and give it a cue, the moment it belongs to, such as “after my morning coffee”. A cue does more for consistency than a target number.
  2. Each day, tick the square under today. Every square is a button: with a keyboard, Tab to it and press Enter or Space.
  3. Use the arrows to look back at earlier weeks or fill in a day you forgot.
  4. Choose how many misses a week the streak forgives. One is a sensible start.
  5. Before you leave, export: CSV for a spreadsheet, or the Thendoo template to keep the habits and cues together.

Why forgiving streaks work better

A strict streak turns one missed day into a loss, and losses make people quit. That’s the moment a habit is most at risk, especially if you have ADHD and some days simply go sideways. A streak that forgives a miss a week keeps your progress visible after a rough day. Getting back on track the next day counts for more than never missing.

The weekly view is deliberate too. A whole year of squares turns the tracker into a judgment. Seven days is short enough to start fresh every Monday.

Make habits easier to keep

  • Attach each habit to something you already do. “After I brush my teeth” works better than “at 22:00”.
  • Make the first move tiny. “Put on running shoes” is the habit; the run is a bonus.
  • Track fewer things. If you’re ticking more than five squares a day, the tracker is becoming a chore.
  • Review on Sundays. If a habit hasn’t stuck after two weeks, make it smaller or move it to a better cue rather than trying harder.

Habits inside Thendoo

In the Thendoo app, habits are written as when, then plans with a tiny first step. Their history shows Done, Skipped and Not done without red marks, and today’s habits sit on the same Today view as your tasks and meetings.

Questions

Why does a missed day not break my streak?

Because one bad day isn't the end of a habit. Research on habit formation found that missing a single opportunity didn't noticeably slow people down. By default the tracker forgives one miss per week, like Thendoo does. You can set it to 0 for a strict streak, or up to 3.

Is my data saved?

No. Everything stays in this page's memory and disappears when you close the tab, and nothing is sent anywhere. Use Export CSV for a spreadsheet, or Download Thendoo template to keep your habits as a file.

How many habits should I track?

Start with one to three. Each one should be small enough to do on a bad day. You can add more once the first ones feel automatic, which usually takes weeks rather than days.

What is the Thendoo template file for?

It's a thendoo-template/v1 JSON file with your habits and their cues, the same format Thendoo uses for its templates. The app can't import it yet, so for now it's a portable record of your plan.
