To use the feature, you need to set your home location by tapping your Bitmoji on Snap Map and then “My Home.” When you head out and want to notify a friend when you get home, open the conversation, tap the Map icon, and then the Home Safe button.

Your friend will receive an automatic alert in your chat conversation once you arrive home.

Snapchat notes that alerts can only be sent to friends you already share your location with. Plus, since location sharing on Snap Map is off by default, no one can see your location or receive a Home Safe alert unless you choose to share it. 

“Whether you’re heading back from a first date, a crowded concert, or a weekend getaway, Home Safe can offer a close friend or family member peace of mind that you’ve made it home safely,” Snapchat wrote in a blog post.

This new feature comes two months after Snapchat announced that Snap Map now has more than 400 million monthly active users.

Snap Map, which launched in 2017, was originally a way for users to see their friends’ locations and browse public snaps from around the world. Over time, the feature has evolved and now offers ways for users to discover local hotspots and find things to do.
