Claim:
1. A method for device-to-device (D2D) application synchronization, comprising: generating, at a first device, a local unique expression that includes a name, one or more user credentials, and a last update time associated with an application registered for a D2D-based application data synchronization service; detecting, at the first device, one or more external unique expressions that are received from one or more peer devices in proximity to the first device and match the name and the one or more user credentials associated with the registered application; identifying, among the one or more peer devices, an update device associated with an external unique expression that includes a last update time more recent than the last update time associated with the local unique expression; and requesting an update to synchronize the application data associated with the registered application from the update device over an out-of-band D2D connection.
