MobileKeep

Create groups for events and invite users from your contacts to join. Add as many people as you’d like to a group. You can even make your group public so other members can add users. Set the radius for the group and be notified when anyone goes too far.

Turn on your tracking to share your location with other group members and alert them to turn on their tracking as well. When group members are outside of the set geofence radius, all members in the group are notified.

MobileKeep allows you to ring any device in your group. When the geofence is triggered, the paired device can offer the ability to pin-in and manually trigger the remote phone to back-up or destroy data.

Features:
Create groups for different events
Geofence notifications when someone leaves your set radius
Enable tracking to share your location
Paired devices can pin in to remote phone to ring, back-up, or destroy data
If you have an Apple Watch with GPS + Cellular you can use it to track alongside your phone so you never lose your phone while you're out on your own. *Note this feature utilizes a workout session on your watch which uses HealthKit, we do not read nor store any of this data it is only used for tracking functionality*
