Is it possible to find out gps location of peoples using same product in particular radius using Google map api in ios application?

I think you would need to write a web service that you post a request to containing a device token and coordinates. The server will maintain a table of device tokens and coords and return a list of devices for devices that google api determines as being within a given distance.
