Use Check In to automatically notify a friend when your Apple Watch has arrived at a destination, when a workout session is completed, or after a specific period of time has passed. You can choose what details they can see if you don’t successfully complete your Check In.
Note: Check In requires the following:
Apple Watch must be near its paired iPhone or connected to the internet using Wi-Fi or cellular.
Both the sender and recipient must have an Apple Watch with watchOS 11 or later or an iPhone with iOS 17 or later.
Location sharing isn’t supported in South Korea and might be unavailable in other regions due to local laws.
Go to the Messages app Digital Crown to open the Smart Stack.
Tap the Check In widget.
Scroll down, then tap Cancel Check In.
On your iPhone, you can change the details you share with your friend during a Check In. See Use Check In on iPhone to let your friends know you’ve arrived in the iPhone User Guide.
