In some examples, the location services utilize global positioning system (GPS). Respective location data of paired client devices is communicated between the paired client devices via a messaging server. ## Claims ### Claim 1 A method comprising: executing, at a first paired client device, a messaging client configured to access a co-location communication service provided by a messaging server, the first paired client device is associated with a first user profile from profiles maintained by the messaging server representing respective users of the co-location communication service; detecting, at the first paired client device using a short range wireless communication component, that a second paired client device executing the messaging client configured to access the messaging server, is within a threshold distance;
