Three seconds, so it doesn't go off by accident
A ring fills while you hold the button, and letting go early sends nothing. If it was sent by mistake, "I'm okay" cancels it.
Free forever
Hold the SOS button for three seconds, and everyone else in your family gets an alert with where you are and how much battery you have. SOS is free, and it always will be.
On iPhone (iOS 16 or later) and Android (8.0 or later).
A ring fills while you hold the button, and letting go early sends nothing. If it was sent by mistake, "I'm okay" cancels it.
The alert goes to every other family member's phone with the place, the street address and the battery level. On iPhone it is marked time-sensitive, so it comes through Focus modes.
When a parent taps "I'm on my way", your child's screen turns green and shows who is coming. Marking the SOS resolved clears it for everyone.
The alert shows a map of where the SOS was sent from, and Directions opens the route in your maps app.
