How to use the iPhone and iPad app

Track

Track is where you run a session. Use the switch at the top to choose Focus or Timer.

Focus

Focus counts up from zero. Tap Start, work, then Stop to save the elapsed time. Pause freezes the clock; Resume continues from there.

Timer

Timer counts down. Set a length with the presets, the dial, or the hour / minute / second wheels (from 1 second up to 23 hours 59 minutes 59 seconds). Start, Pause, Resume, and Stop work the same way as Focus. Reset restarts the countdown without saving. When time is up, the system can alert you on the Lock Screen.

Sessions shorter than one second are not saved.

Categories and sub-categories

A category is a workspace (for example Personal or Work), with its own icon and color. A sub-category is a tag on a session (for example Writing or Deep work), with its own color.

Dashboard

Dashboard shows how you spent time. The category chip at the top is only for browsing — it does not change the category on Track.

Lock Screen and alerts

Focus can show a Live Activity on the Lock Screen (and Dynamic Island on iPhone) with Pause and Stop. Timer uses a system countdown alarm when AlarmKit is available (iOS 26+); otherwise a notification fires at zero.

Allow Live Activities, notifications, and Timer (AlarmKit) for Time Keeper in iOS Settings if the Lock Screen stays blank or the countdown does not alert.
