Have you ever wondered when you last did something? Your last vacation, your last call to your parents, or the last time you changed your toothbrush. Last Time makes tracking things easy and enjoyable, so you won't forget what matters to you. Tracking ideas: - Last time you watched that movie. - Last time you hung out with your friends. - Last time you visited your parents. - Last time you played with your children. - Last time you saw the dentist. - Last time you read a good book. Not just the good things — you can also track what you want to quit or cut down on, like smoking or running late. The only limit is your imagination. You will find you manage your time better just by knowing when you last did something. Features: - Event tracking: see how long it has been since the last time, counted in days. - One tap to log: mark something done from the list, with a note or on a date you choose. - Your own icons: give every event a symbol from the full SF Symbols library, in the color you pick. - Grouped by due date: Overdue, This Week and Later, worked out from how often you actually do each thing. - History: every entry in order, with the gap between them, your average, and when the next one is due. - Morning Digest: one notification a day, and only when there is something worth saying. - App Lock: keep your events behind Face ID, Touch ID or your device passcode. - iCloud sync: your events on all your devices. - Shortcuts and Siri: mark an event done, or ask when you last did something. - Export: take everything with you as a CSV. - Light and dark: follow the system, or pick one. - iPhone and iPad.

Verdict

The call

The clearest difference is in-app purchases: Koyomi at none against Last Time Tracker's 3. Koyomi also leads on rating (5.0 vs 4.6) and price ($1.99 vs $5.99). Last Time Tracker's advantage is update cadence (daily vs every 5 weeks) and ratings volume (636 vs 2). On ads and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Koyomi holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Last Time Tracker has 636 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 82% of Last Time Tracker's written reviews are positive against 58% of Koyomi's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Last Time Tracker ships an update daily, Koyomi every 5 weeks. The most recent releases landed on October 21, 2026 and October 19, 2026 respectively.
