Tsuzuku: Habit Streak Tracker
Habit calendar, steps & widget
$0.99 · Designed for iPad. Not verified for macOS.
New: rest days. Mark a day you can't make it as Rest and your streak stays intact. A gentle note appears when yesterday wasn't logged. Unlimited habits, all undoable.
No cap on tasks. Every mistap is undoable. Your history never disappears.
A habit tracker and a to-do list in one screen, bought once.
No ads, no in-app purchases, no subscription.
■ There is no limit on how many tasks you keep
Not six, not twenty-four. No pages to swipe through either — everything due today sits in one list. Morning routines, work to-dos and weekend chores can live in the same place.
■ Ticks itself off with Apple Health
Tasks like "walk 8,000 steps", "exercise 30 minutes" or "meditate 10 minutes" are checked off automatically on the days your Health data reaches the goal.
Choose from steps, exercise minutes, mindful minutes, walking distance, active energy and water. The last 7 days are checked each time you open the app, so days you forgot to open it still fill in.
Automatic checks can be undone like any other, and an undone day stays undone.
Health data is only read. Nothing is written to Health, and nothing leaves your device.
■ A mistap is always undoable
An Undo button appears at the bottom of the screen the moment you tick something. Noticed later? Swipe the row left to take one back. No shaking the phone, no hidden gestures to memorise.
■ Rest days keep your streak
Ill, travelling, or simply out of time? Swipe a row left and choose Rest. That day drops off the schedule and your streak does not break. Long-press a date in a task's calendar to rest a past day. Logging the task removes the rest automatically.
■ Fill in the days you missed
Forgot to log yesterday? The app tells you the next morning. Tap a past date at the top to fill it in. Set a start date in the past and an existing streak carries over.
■ A half-done day counts as half
If your goal is three times a day and you managed two, the app records two. It does not throw the day away. Going over the goal is recorded too.
■ Built so your history does not vanish
• Everything is stored on your device. No account, no sign-in
• A backup is taken automatically once a day, keeping the last seven
• Export and import a file whenever you like — that is how you move to a new phone
■ Log straight from the Home Screen
Tap the ring on the widget and it is recorded. The app never opens. Small, medium and large Home Screen widgets plus a Lock Screen widget.
■ Repeats that match how you actually work
• Every day
• Chosen weekdays (Mon / Wed / Fri and so on)
• N times a week — any days, as long as you get there
• N times a month — any days within the calendar month
• Every N days, whatever interval you want
• One time only, which leaves the list once done
■ Reminders, only as many as you want
Give a single task as many times as you need — morning, noon and night for medication, for example. One switch in Settings stops every reminder at once. We ask for notification permission only when you add your first reminder.
■ Progress you can actually see
• Current streak and your best run
• Completion rate over the last 30 days
• Lifetime totals, in times or in hours
• A monthly calendar large enough to read
Today and rest days never break your streak. This app is not built to rush you.
■ For night owls
Move the start of a new day to 3:00 or later, and you can still tick off "today" after midnight.
■ What this app does not do
• No ads
• No in-app purchases and no subscription
• No endless review begging — we ask once, at a milestone
• Your entries never leave the device. Only anonymous usage stats are counted (off in Settings)
■ Before you buy
This version has no cloud sync and no Apple Watch app (steps and workouts recorded by Apple Watch still count through Apple Health). Your records live on one device. To move to a new phone, export a backup file from Settings and import it on the other side. We would rather leave sync out than ship the version that loses your data.
One purchase. That is the whole story.

Ratings & Reviews

• Settings now has a "Connect to Apple Health" button. It asks for all the items (steps, workouts and more) in one go, and the app now appears in the Health app's list of apps.
• Settings now shows whether you're connected, and how to review permissions later.
