A computer-implemented method for synchronizing mobile computing platforms may include (1) identifying a set of applications installed on a mobile computing platform, (2) detecting a request from an additional mobile computing platform to synchronize the additional mobile computing platform and the mobile computing platform with respect to the set of applications, and then (3) synchronizing the additional mobile computing platform and the mobile computing platform with respect to the set of applications by (a) querying an application-matching engine to determine an equivalent set of applications that corresponds to the set of applications on the additional mobile computing platform and then (b) directing the additional mobile computing platform to download the equivalent set of applications. Various other methods, systems, and computer-readable media are also disclosed.
