Abstract: An apparatus and a method for managing an application of an electronic device are provided. A method of operating a first electronic device includes, when an update is detected regarding an application provided to at least one second electronic device, generating an update notice including target information for the application to be updated; transmitting the generated update notice to the second electronic device; and transmitting update data of the application to a second electronic device that has responded to the update notice. A method of operating a second electronic device includes receiving an update notice including target information representing an update object from a first electronic device; determining an application that needs an update operation among already installed applications in the second electronic device based on the target information of the received update notice; and receiving update data from the first electronic device so that the determined application is updated.
