You can set up your app to do over-the-air updates. This can be as simple as shipping an updated JS bundle or delivering just patch diffs for it to apply. So long as your code changes are JS-only and don't involve any native code, you can push an update.

People are already used to being able to do things like phased rollouts, automatic rollbacks, and hotfix deployments for webapps and API services. OTA updates let you do something similar for mobile.

It's against the ToS from the stores to do this for notable feature changes that impact what the user sees, but for things like fixing crashes, bugs, or applying security updates, it's a game-changer.
