You can, for certain classes of application, and for certain types of tasks (like background downloads). It’s entirely managed by the OS, and is often reduced or suspended entirely under Low Power mode. But Apple allows for other kinds of wake notifications and is usually pretty good with Push Notifications due to carrier partnerships. That said, Apple does intentionally make certain apps a lot harder: https://stackoverflow.com/questions/35388086/is-there-a-way-to-wakeup-suspended-app-in-ios-without-user-or-server-interventio https://stackoverflow.com/questions/35388086/is-there-a-way-... And... well, it rarely allows apps that duplicate built-in functionality on the App Store. So most iOS users stick to default apps. But at least one app takes advantage of Apple allowing the microphone in the background to create a “smart” alarm clock which Apple has featured as the App of the Day: Sleep Cycle alarm clock http://www.sleepcycle.com http://www.sleepcycle.com

And... well, it rarely allows apps that duplicate built-in functionality on the App Store. This is such an old meme and there are plenty of existence proofs that it isn’t true. There are third party apps for every single app on iOS including navigation, podcasts, mail, music players, calendars, password managers (with integration APIs specifically for them as of iOS 12), weather, notes, etc.

I'm not saying the rules aren't much improved from what they used to be -- it's been years since the simple advice was "don't ship something we ship," but ... at its core, it's still somewhat true. You have to ship an original app -- and all of the app categories you mentioned have truly original apps on the App Store already.

Don’t simply copy the latest popular app on the App Store, or make some minor changes to another app’s name or UI and pass it off as your own.

      I was citing rule 2.5.4 with that list of approved background app categories, unless you can name exemptions...

        Well unless you think that Apple added the APIs that I linked to and added settings to allow you to disable background processing (that doesn’t apply to the categories) you mentioned, which do you think is the more appropriate interpretation to what is allowed - the rules or the API documentation?
