๐Ÿ”ฅ Habit tracker for iPhone

Green for yes.
Red for no.

Square Streak keeps habits simple. Check off each day with one tap, watch your streak grow, and earn new looks as it gets longer.

Free to start. Pro is a one-time $3.99. No subscriptions, no account, no tracking. Syncs with iCloud.

One tap a day.
That's the whole job.

Every habit gets a card with its streak, today's โœ“ and โœ—, and a strip of the last two weeks. Miss a day? Step back with the day picker and fill it in.

  • Green for yes, red for no. Or switch to a single button that cycles through both.
  • Rest days for weekends or holidays, so time off doesn't break a streak.
  • Reminders that only nudge you if you haven't checked in yet.
  • In Sync counts the days every habit was green together.

Interactive widgets mark today without opening the app. The large widget shows the whole month, and you can tap any day to fill it in.

  • Small, medium and large home screen widgets, plus Lock Screen widgets.
  • System, Light or Dark widget themes.
