Share live locations with family, friends and trustworthy people all the time!

Place Alert:
Set two geofences/places for each member and get notifications when the members enter or exit the geofences!

Change members' geofences on your own device in every 3 hours if necessary. That way, you can set geofences to possibly all places your members get to.

If you say "I only need to see my kids' locations, and do not need to let them see mine. And me and my spouse will share each other's location.", then try using Lilac Location Sharing app.
With Lilac, you can separate people whose locations you see and people who see your location.

Have up to five members(people whose locations you see) and unlimited number of viewers(people who see your location).
Add and remove members and viewers easily with just few tapping of buttons.
