Stay connected with the people who matter. SnapLo lets you share your real-time location with friends you invite and see each other on a live map — so you can coordinate, meet up, or just know everyone got there safely. Sharing is always consensual and fully under your control. LOCATION SHARING • Share with friends you invite — Connect using a simple invitation code, then see each other on a live map in real time.

When you remove a connection, neither side can see the other anymore. • Consent first — SnapLo is built for consensual location sharing between people who know and trust each other. It does not track your location in the background (location is used only while the app is in use). • See it on the map — A clean map, powered by Apple Maps, shows you and your connected friends and helps you find places nearby.
