A first client device executes a plurality of actively running applications, each having one or more checkpoints, each checkpoint identifying an execution breakpoint at which a respective application can be suspended and subsequently resumed. The first client device detects a transfer triggering condition, stores an application state for each of the plurality of actively running applications, and transmits the stored application state for each of the plurality of actively running applications to a second client device or system. The stored application state for each respective application of the plurality of actively running applications corresponds to a checkpoint of the respective application. Optionally, the transfer triggering condition includes presence of the second client device or system within a predefined proximity of the first client device or system, wherein the predefined proximity is a predefined proximity for near field communication.
