Crash sharing
From the app’s English Help & Guide · Reference release 1.0.19
Overview
Tap the heart-bolt icon in the Today toolbar to open Quick Needs and broadcast a one-tap signal to your carer. The icon is only visible once you’ve set up Carer Sharing and configured your Quick Needs menu — so the dashboard never nags. The same broadcast works from your home-screen widget, lock screen, watch face, or by saying “Hey Siri, tell Harry I crashed in Metered”.
