30 days · iPhone · Free to start

Big changes start with 30 days.

Turn any goal into a simple 30-day challenge. Check in daily, build your streak, and watch the grid fill up. A month is long enough to make a habit stick, and short enough to actually finish.

Why people choose this habit tracker

Why 30 days

A month you can actually see the end of.

“Someday” is not a deadline. Every habit gets its own 30-day grid, so progress is a thing you can look at rather than a feeling you have to trust.

Fill it, and we throw you a party — confetti, a recap of your stats, and a shareable card. Then day 31 is just the start of the next one.

30-day challenge · Drink water

Done days fill in. Missed days stay an empty outline. Future days aren’t shown at all — there is nothing to feel behind on.

Home Screen widgets

Check in without opening the app.

The fastest habit app is the one you never have to launch. Tap a habit straight from your Home Screen and get on with your day.

  • Small, Medium and Large widgets with one-tap check-in
  • A Control Center control for instant access
  • Siri & Shortcuts — “Check off Drink Water” just works
  • Mark a habit done straight from its notification

Stats

See your streaks grow.

Numbers you can act on, not a dashboard you have to decode. Per-habit streaks, a completion rate, and a year of activity at a glance.

  • GitHub-style yearly activity heatmap
  • Weekly bar charts over the last 12 weeks
  • Current streak, best streak and completion rate per habit
  • Perfect-day tracking across every habit at once

Templates

Start in seconds.

Pick a preset and you are on day 1 before you have finished thinking about it. Or build your own from 60+ icons and a full palette.

  • Walk, read, meditate, drink water, sleep early, journal and more
  • Every day, specific weekdays, or X times per week
  • Smart per-habit reminders, set as you create
  • An optional evening summary that only fires if something is left

Day 30

Finish something.

Most habit apps only ever tell you how far you still have to go. This one has an ending, and it makes a fuss about it.

  • Confetti and a stats recap when a challenge completes
  • A shareable progress card for the group chat
  • Streak milestone toasts along the way
  • Rich haptics that make every check-in satisfying

Questions

Before you download.

Do I need an account?
No. There is no sign-up, no login and no email field anywhere in the app. Open it and start on day 1.
Does it work offline?
Entirely. Every check-in, streak and chart is computed on your iPhone. The app has no servers to talk to, so it works on a plane, on a trail, or with the SIM out.
What happens to my data?
It stays on your device. Nothing is uploaded, and there is no analytics profile tied to you. You can export a complete JSON backup or a CSV of every check-in at any time — including on the free tier.
What if I miss a day?
The day stays an empty outline in your grid and the streak resets, but the challenge carries on. Rest days on a weekday or times-per-week schedule never break a streak.
What happens on day 30?
You get confetti, a recap of your stats and a shareable progress card. Then you can start the next 30 days on the same habit, keeping your lifetime totals.
Is the free version crippled?
No. Three habits, daily schedules, streaks, the 30-day grid, all ten templates, a reminder, the Small widget and full data export are free forever. Pro lifts the limits; it does not unlock the basics.
Which devices are supported?
iPhone, with Home Screen widgets, a Control Center control, Siri and Shortcuts. The app is available in English and Tiếng Việt.
