Use the Find My app on your iPad.
Tap People at the bottom-left side of the screen, then tap the name of the person you want to be notified about.
Below Notifications, tap Add, then tap Notify Me.
Choose whether you want to be notified when a friend arrives at or leaves a location.
Choose a location, or tap New Location to create a new location and set a location radius.
With a larger radius, you’re notified when your friend is near the location instead of right at the location.
Choose whether you want to be notified only once or every time.
Tap Add, then tap OK.
Your friend gets an alert after you set the notification.
If you set a recurring notification, your friend must approve it before it’s set. They get an alert asking for approval when they arrive at or leave the location you chose for the first time.
You can receive a notification if your friend or family member isn’t at a specific location during a set schedule. For example, you can be notified if your child isn’t at school during school hours.
