Abstract: The present invention discloses a method, a system, and an apparatus for sharing application information. The method receives match request sent by a mobile terminal X upon receipt of a share instruction of a user. According to the match request, the method determines whether there is a mobile terminal which is matched with the mobile terminal X among other mobile terminals that send match request, and if a mobile terminal is found, sends a success message. When a server receives identifiers of applications to be shared sent from any one mobile terminal of the matched mobile terminals, the method determines whether the other mobile terminal of the matched mobile terminals is connected to the server, if the other mobile terminal is online, obtains relevant information of the application corresponding to each identifier respectively, and sends the obtained relevant information to the other mobile terminal.
