A host application installed on a computing device detects that the computing device is in proximity of a location associated with another application that can be installed onto the computing device. As a result of the computing device being in proximity of the location, the host application obtains, from an application vending server, application code for the application. The host application uses the application code to install the other application onto the computing device. If the host application detects that the computing device is no longer in proximity of the location, the host application uninstalls the other application from the computing device.
