I'm not talking about sharing state with your webserver, I'm talking about two apps on your phone sharing state directly with each other without ever leaving the device or becoming accessible to a third party.

Desktop operating systems have a slew of ways to facilitate this, and the mobile gatekeepers keep eroding them. They're also terrible at dependency management (a completely solved problem in real package managers), which discourages creating apps that depend on other apps.

There are still ways to do any given thing, but if you make it harder then you make it rarer.
