A system is configured to perform operations that include determining a first set of modular features corresponding to a first version of a service provider application and a second set of modular features corresponding to a second version of the service provider application. An original version of the service provider application may have been downloaded from an application store. The operations further include identifying, based on a comparison between the first set of modular features and the second set of modular features, a new set of modular features. The operations also include applying the new set of modular features to the first version of the service provider application. The applying may be based on determining that the new set of modular features supports predefined interface templates and corresponding interpreters. As such, the operations may be performed without communicating with the application store.
