Systems and methods relating to location-based applications, such as widgets, are disclosed. In general, in one embodiment, a mobile device obtains a list of applications associated with a current or anticipated location of the mobile device from a centralized or distributed application service. One or more desired applications to be activated are either manually or automatically selected from the list of applications associated with the current location or the anticipated location of the mobile device. The mobile device then activates the one or more desired applications. Optionally, for each desired application that has been activated, the desired application may be deactivated once one or more deactivation criteria are satisfied.
