Know exactly
when you're off.

A dynamic clock-out calculator for people whose shifts don't run on fixed alarms.

Off Clock solves one problem: if your clock-in time moves every day, a fixed 5:00 alarm is useless. It continuously recomputes your clock-out time from the moment you clock in, your target hours, and a payroll rule that only forgives the first 30 minutes of break — every minute past that pushes your clock-out back one-for-one.

  • Live Activities & Dynamic IslandReal-time break and clock-out status on the lock screen, no unlock required.
  • Survives a force-quitEvery timer is recomputed from stored timestamps, never a running clock — killing the app can't desync it.
  • Haptic + notification alarmsCoreHaptics-driven alerts when a break or your target hours expire, with per-alarm mute controls.

Dynamic Island reflects whichever state is selected above — try switching to a break tab.
The one formula the whole app is built around
Off Clock At = Clock In + Target Hours + max(30 min, Total Break Taken)

The first 30 minutes of break are free — standard for a lot of hourly payroll systems. Every minute beyond that pushes the clock-out time back one-for-one, live. The Open Break screen recalculates this every second, so the moment you cross the 30-minute mark, the estimated clock-out visibly starts climbing.

Lock screen & Dynamic Island

An ActivityKit Live Activity keeps the running timer and clock-out estimate visible without unlocking the phone — compact pill, expanded view, and lock screen widget all driven from one shared timeline.

Timestamp-based timers

No timer ever stores an accumulating delta. Every displayed duration is recomputed from stored Date values on each foreground/tick, so a force-quit or hours in the background can't drift the numbers.

Editable timeline

Forgot to log a break? Every entry in the day's timeline — clock-in, breaks, clock-out — is retroactively editable inline, with overlap and ordering guards so edits can't corrupt the running calculation.
