A Check-in is a simple way to let one or more of your Contacts know where you are. To perform a Check-in, press the button on the front of your device once. A single, quick press is all you need. You will feel a vibe confirming the Check-in was sent.
Your Contacts can use the link they get through text and email to view the Check-in location on a map. Check-ins remain viewable indefinitely from the SMS and email link.
