Kizami records whether you did it, at the time you set. What you kept and what you didn't are kept with the same weight. Neither can be deleted or rewritten afterwards. The app writes the misses, not you In most habit trackers, a day you missed is an empty square. An empty square can be filled in tomorrow. Kizami writes a line into the ledger — "missed" — once the deadline passes. Entries are accepted only from 30 minutes before the time until the deadline; after that, nothing can be added. Forgetting does not quietly become nothing at all. The stake is a record, not money There are services that charge you when you fail. They appear to work, but they need a card on file, a monthly payment, and trust in a third party. Kizami puts the same irreversibility in a ledger on your own device. Nothing is sent anywhere, and no one collects from you. It simply stays written. You can explain. You cannot rewrite. You can add a reason to a slot you dropped — forgot, no time, unwell, not up to it, other. But it is added as a separate line; the original line does not move. There is room to say your piece. There is none to change what happened. It cannot be erased. That is the design. Saying this first: the ledger has no delete and no edit, and the screens carry no path to one. If you record something by mistake, you add a note rather than remove the line. The ways around it are closed too. - Nothing can be backdated (30 minutes before, until the deadline) - Stopping a commitment does not remove its past entries - Lowering a goal does not change a past "18 / 30" — it stays partial - A pause can only be set for today or a future date - Entries made while the device clock looks rolled back are marked Recording itself stays free Today's screen, the ledger and the notifications all work without paying, and every single entry in the ledger is readable. One payment (no subscription) opens three things: - As many commitments as you want (free: up to 3) - Stats and monthly reports over the full history (free: last 30 days) - Recording from Apple Watch There is a 7-day trial. It starts when you tap to start it, so it does not run down while you are only looking. Also - Three ways to count: repetitions (30 reps), time (15 min), or simply done / not done - Not all-or-nothing: 18 out of 30 is kept as partial - On the 1st of each month, the previous month is sealed as a report. That does not change either - 日本語 / English / 简体中文 / 繁體中文 What it does not do - Notifications are local iOS notifications. Delivery is up to iOS, so they cannot be guaranteed. If one does not arrive, the slot past its deadline is still recorded the same way - The timed notification comes from the iPhone. If the iPhone is off, the watch alone will not sound (you can still record from the watch alone) - Data lives on the device. Nothing is sent to a server. There is currently no sync across devices - This is not an app that gives exercise, health or medical advice
