An electronic communication device and method for crowd-based application synchronization. The device includes a display, a memory storing a first application, a transceiver, and an electronic processor. The electronic processor is configured to associate the electronic communication device with a first talk group, determine a first function in which the first application is configured to perform, and receive, via the transceiver, information regarding a number of members of the first talk group that are using an instance of a second application to perform the first function. The electronic processor is further configured to automatically present, based on the information, on the display, a running instance of the second application or a selection mechanism for the second application.
