Alarm behavior on Apple Watch

When WatchKeeper has an active handover alarm, the Apple Watch app can switch into a dedicated alarm view that highlights the incoming watch and gives you quick actions from your wrist. This is designed to make a watch change easier to notice and easier to handle without going back to the phone immediately.

On Apple Watch, the alarm view shows the trip name, the incoming watch crew, the scheduled handover time, and how overdue the handover is. The screen uses a prominent alarm presentation so it stands out when attention is needed. From there, you can respond directly with Acknowledge, Delay 15, Delay 30, or Delay 60.

These watch actions are sent back to the iPhone, which remains the main source of truth for the schedule. If the phone is reachable, the action can be confirmed quickly. If the phone is temporarily unavailable, the watch can queue the action and try to deliver it when the connection returns. In that case, the watch may show that confirmation is still pending.

This means the Apple Watch can help you react quickly, but the final schedule change still depends on the iPhone receiving and applying that action. If the watch shows that the phone is unavailable or the action is waiting for confirmation, check the iPhone as soon as practical to make sure the alarm update has been applied.

What to Expect

• An active handover alarm can open a dedicated alarm screen on Apple Watch.
• The watch can show the incoming crew, handover time, and overdue time.
• You can acknowledge or delay the alarm directly from the watch.
• Alarm actions still depend on the iPhone to confirm and apply the schedule change.

If the Phone Is Not Available

• The watch may queue the action locally.
• You may see a message that the alarm action is not yet confirmed.
• The change should be checked on the iPhone once it reconnects.

Best Practices

• Keep the iPhone nearby if you expect to manage alarms from the watch.
• Test acknowledge and delay actions before departure.
• If a watch action seems stuck, open WatchKeeper on the iPhone to confirm sync.
• Treat Apple Watch as a fast alarm companion, with iPhone as the main control point.

The Apple Watch alarm flow is meant to reduce friction during handovers: quick to notice, quick to act on, and backed by the iPhone for final schedule updates.
