How the challenge works

  1. Pick 3 small habits. Start with the suggestions, such as a few minutes of planning, 20 minutes of movement or some time to read or reflect, or swap in your own. Set the days and times before you join.
  2. Check in once a day. Complete any one of your habits and the day counts. Your challenge sits at the top of Today with a row of dots that fill in as you check in, and you can tap it to see which day you're on.
  3. Reach 15 of 21 days. You get a note at the halfway point and a celebration when you complete the challenge. If you don't quite get there, you get a kind summary instead of a failure screen.

Why 15 of 21, not a perfect streak

Streaks are brittle: miss one day and the number resets to zero, which is often when people quit. The challenge counts days you showed up, so one bad Tuesday doesn't end it. That's the same idea behind HabitScore, TrackHabit's 0–100 measure of how consistently you follow through.

And 21 days isn't a magic number. Research shows habits take different amounts of time for different people, which is why we treat it as a focused window to get a routine going. If you're curious, read the 21-day habit myth, or why simply tracking a habit makes you more consistent.

Your choice, always

Leave a challenge at any time and keep the habits as a regular goal, or delete it. A challenge doesn't use up your free goal, so you can join without giving anything up.

Questions about the challenge

What is the New Year Reset Challenge?
It's a 21-day habit challenge inside the TrackHabit app. You choose 3 small habits, check in once a day by completing any one of them, and reach 15 of the 21 days to complete the challenge.
Do I have to complete all 21 days?
No. You complete the challenge by checking in on 15 of the 21 days, so a few missed days don't end it. If you don't quite get there, you get a kind summary instead of a failure screen, and your habits stay yours either way.
What counts as a check-in?
Completing any one of your challenge habits on a given day. You don't need to finish all three every day.
Can I choose my own habits?
Yes. The challenge starts with a few small suggestions, and you can swap in others and set the days and times before you join.
When does it start?
Joining opens on December 18, 2026, and the challenge runs in January 2027. If you join before January 1, your 21 days start on January 1 by default, and you can choose to start the day you join instead.
Does a challenge use up my free goal?
No. A challenge doesn't use up your free goal in TrackHabit.
Can I leave a challenge?
Any time. You can keep the habits as a regular goal or delete them.
Is 21 days really how long it takes to form a habit?
Not exactly. The research shows habit formation varies a lot from person to person. The 21 days are a focused window to start building a routine, not a promise that the habit is automatic by day 22. Our post on the 21-day habit myth covers what the research says.
