Why a live app needs work every month
An app that was perfect at launch will not stay that way untouched. Apple and Google each ship a major operating system release every year, and both change permission prompts, background limits and privacy rules as they do. Stores also raise the minimum target version they accept, so an app that is not updated can be blocked from new installs or warned for removal.
Third-party libraries age too. Payment SDKs, analytics tools, map providers and push services release breaking changes, and old versions pick up known security flaws. Meanwhile your own backend and APIs change. A field renamed on the server can quietly break an older version of the app that thousands of people still run.
Maintenance is the routine that absorbs all of this. Without it, the cost does not vanish, it arrives later as a rushed fix at a bad moment, usually just before a deadline from a store.
