Question

When developing an application like Find my friends, when you can see multiple people on a map move live (say, in a defined area like the beach or a park), what is the key technologies to use ? I was thinking GameKit to pair devices instead of passing through a central server, which might be slower. But is GameKit really doing peer to peer connectivity ? What maximum distance will allow this ? Is there another better way to track position live ?

Answer 1

GameKit may not work – due to limitations with Bluetooth range which is typically 30-40 feet

You may want to consider a remote server that processes the locations from the various clients and clients get the other client locations from the server.
