A system for dynamically updating modules used by a mobile application configured on a user device may enable the more efficient use of system resources and improve the user experience. A current state of the mobile application may be determined and provided to a mobile application module service that may execute a rules engine using input based on the current state of the mobile application. The rules engine may generate a current module state for the mobile application that the mobile application can use to download currently needed modules and/or delete modules no longer needed.
