Snapchat introduced an aptly named Home Safe feature that lets your loved ones know you've made it home safely after an outing. It sends a one-time alert to contacts you've already shared your location with. However, location sharing is disabled by default, so it is a feature you will activate by your own choice.
You can enable it by setting up your home location. Tap on your Bitmoji on the Snap Map, and then select My Home. So, next time you head out and want to keep a trusted contact in the loop, open your conversation with them. After that, tap the Map icon and select the Home Safe button. Your friend or family member will receive an automatic alert in the chat once you get home.
