1. A method, comprising operations of: querying an app database for an app update schedule upon receipt of a request from a client for an update check, wherein the request provides a deployed app version number for an app executing on a client device; parsing the app update schedule with a parsing utility to obtain a current app version number of the app; determining that the deployed app version number is older than the current app version number; obtaining the current version of the app from an app database using the current app version number; conducting a dependency analysis of the current version of the app using a scanning utility that outputs a hierarchical tree diagram of dependent code modules, wherein the hierarchical tree diagram identifies a name and a code version number for each dependent code module; using the name and code number for each dependent code module to obtain all code version numbers for the dependent code module from the code database; determining whether at least one code version number for a dependent code module is later than the code version number for the dependent code module in the hierarchical tree diagram; and creating an updated app using newer source code for the at least one dependent code module with the later code version number, wherein each of the operations is performed by one or more processors.
