It seems that Apple Notes can connect to IMAP services such as Google. Is that the only way to sync with Notes? We have a notes app and would like to connect directly. Same with Reminders. Previously access to Reminders was available via iCloud sync but that seems to have stopped. Is it available via EventKit?

We are developing an app with different versions for iOS, iPadOS, and MacOS. There is no shared code, but they do sync together. Can we give them all the same name? A few other points: The app will be distributed for free, with a subscription for higher levels. We are fine with a unified purchase capability. In the past, App Review has informed us that we must have different names, but we see other common apps use the same name on their different platform versions.
