Distancer

A real-time GPS tracker for car convoys, bike rides, and any other organized groups, including hiking trails. The service is designed specifically to keep groups together in heavy traffic, on rough terrain, or along complex routes. It monitors the exact distance between all participants in meters and instantly activates an audible or visual alert if the distance exceeds the limit. It helps the leader (the head of the convoy or the guide) slow down and wait for stragglers. It launches in one click in the app or browser and requires no registration. Clicking on a participant will show their location on Google Maps. Clicking on a participant's icon will open a map showing the locations of all participants.
