How to Use iPhone Check In to Let Family Know You Arrived Safely

Check In is a safety feature Apple added in iOS 17 that automatically sends a message to a trusted contact when you arrive at your destination. If you don't arrive on time — or if your iPhone detects that you've stopped moving — your contact is notified so they can check on you.

This is especially useful if you're driving home alone at night, going for a walk by yourself, or traveling somewhere unfamiliar. Instead of having to remember to text "I made it," Check In handles it automatically.

Here's how it works: you start a Check In from inside the Messages app before your trip. You type how long you expect the journey to take, and the person you're messaging gets a progress update. When you arrive, they get a confirmation. If your iPhone notices you aren't moving toward your destination or your phone battery dies, your contact is sent your last known location along with other helpful details.

Check In shares only what's necessary — it does not send your real-time location throughout the trip, just a check-in message when you arrive (or an alert if something seems wrong). Your contact must be using iPhone and Messages to receive Check In notifications.

You can use Check In for short trips or longer journeys. The feature asks for your estimated arrival time, and you can adjust it on the fly if your plans change.
