Features
Keizoku is a minimalist habit tracker for iOS and Android with a clean, notebook-inspired design. Inspired by the Japanese philosophy of keizoku wa chikara nari (perseverance becomes strength), it strips habit tracking down to what actually matters: showing up consistently, in a space that feels good to open every day.

Free for everyone
No ads and no time limit. Track up to five habits for free, for as long as you like.
Notebook-Style Habit Grid
Track daily habits on a clean, paper-like monthly grid. Tap a box and it's done. Switch between vertical and horizontal layouts and turn on weekday labels if you like seeing Mon, Tue, Wed down the side.
Make It Look Like Yours
Pick a drawing style (Clean, Sketchy or Rough) and a completion mark: an X, a scribble, a checkmark or a hand-drawn circle (○). You can change both any time in Settings.
Daily Reminder
One gentle reminder at the time you choose. A nudge to keep your routine on track, not an avalanche of notifications.
Progress at a Glance
Tap a habit's name to see it month by month or across the whole year. Gaps show up as blank boxes and the rest of your progress stays right where it was.
Sounds and Milestones
Optional sounds when you mark a habit done and small milestones along the way for the days you keep showing up.
Offline-First, No Account
Your data stays on your device by default. No sign-up, no email and no internet needed to track your day.

Common questions
Does Keizoku work without an account?
Yes. Keizoku is offline-first and doesn't require an account. Your habit data is stored locally on your device. There's nothing to sign up for and no email to give.
Does Keizoku have widgets?
Yes. Keizoku Pro includes home screen widgets on iOS and Android so your habits are in view without opening the app. They use the same notebook look as the app.
Can I track a habit only on certain days?
Yes, with Pro. Custom schedules let you choose which days a habit shows up, like only weekdays or only Monday, Wednesday and Friday.
How does iCloud sync work in Keizoku Pro?
On iOS, Keizoku Pro uses your own iCloud account to sync habits across your Apple devices. The data goes through your iCloud, not through Keizoku's servers, so we never see your habits.
Can I switch between Free and Pro at any time?
Yes. Free users can upgrade to Pro whenever they want, and Pro users keep all their data if they switch back to Free. Your existing habits aren't deleted, but you'll be limited to viewing the first 5 if you exceed the Free tier.
What's the difference between Keizoku and other habit trackers?
Most habit trackers focus on streaks, gamification, or detailed analytics. Keizoku focuses on a single thing: a clean, paper-like monthly grid where you mark each day done. If you want a focused habit tracker that stays out of your way, Keizoku is built for that. If you want gamification or detailed reporting, other apps will serve you better.
How many languages does Keizoku support?
Keizoku is available in 39 languages. The app adapts to your device language automatically.
