Vibrations

Each alert has its own vibration, so you know what’s happening without looking at your watch.

What each one means

The rule for turns: the long vibration is on the side you turn to (first for left, last for right).

Lap and target vibrations can be turned off for a single activity in This activity › Vibrations.

With the screen off

Alerts vibrate even when the screen is off or dimmed. On top of that, since 0.3 every alert that vibrates also turns the screen on for about 5 seconds, so you can see what’s going on without raising your wrist. In earlier versions you had to raise it. Coming in 0.3
