Build a Friend Location Sharing App

Location-based apps offer a perfect blend of real-time communication, maps integration, and privacy management. A friend location sharing app teaches you how to use GPS, geofencing, live updates, and map rendering—skills that are highly relevant for modern app development.

Let users opt-in to share their real-time location with selected friends. Display live positions on a map, offer distance-based alerts, and ensure granular control over sharing—making the app ideal for meetups, group travel, or safety tracking.

Users sign up and create friend connections. When sharing is enabled, their location updates periodically and is broadcast securely to those friends. Users can view locations on a map interface, receive alerts when someone’s nearby, and manage their sharing status.

• Users sign up and connect with friends through invites or username lookup.
• Enable location sharing with specific friends—temporary or permanent.
• Locations are plotted on a live map that updates every few seconds.
• Proximity notifications are triggered when users are within a defined radius.
• Users can stop sharing or block visibility at any time from the privacy panel.
