Claude on iOS

Unless I'm missing something—certainly likely—there is very little connection possible between the iOS client and anything or anywhere productive. At the very best, it can write to Reminders. It can't read from or write to anywhere that the MacOS might store text, so it's hard to integrate them. I'm not looking for anything really involved—I'm writing, not coding.

What do people actually use the iOS version (or the web version) for? Just Reminders and email drafts?
