Tsuzuku: Habit Tracker & ToDo

Keep as many habits as you like. Any mistap is undoable, a day you forgot can be filled in later, and your history never leaves the device.

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.

■ 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.

■ Fill in the days you missed

Tap a past date in the strip at the top and the whole screen moves to that day. You can also open a task and tap a date in its monthly calendar. Set a start date in the past and an existing streak carries over from day one.

■ 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 • 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 never breaks your streak. A streak only ends after a scheduled day passes unmet. 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 • No data collection. Nothing is sent anywhere

■ Before you buy

This version has no cloud sync and no Apple Watch app. 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.
