iOS apps on macOS would bring hope for Apple Watch, Apple Health support on Mac

With Apple rumored to bring support for universal apps in iOS 12 and macOS 10.14, the move could also be good news for the Apple Watch, potentially untethering it from the iPhone for both setup and sync.

As an emerging and limited platform, the Apple Watch currently requires a connected and paired iPhone to set up. In addition, health data is also synced through the Apple Health app, which is exclusive to iPhone.

Notably, both the Watch and Health apps are not available on the iPad, nor are they available on macOS. This despite the fact that improvements in watchOS, as well as the addition of LTE connectivity in Series 3 hardware, have allowed the Apple Watch to become more independent from the iPhone.

This week, a new rumor has alleged that Apple will let iOS apps run on the Mac starting with software updates next year. The major change to Apple's systems is said to be known internally as project "Marzipan."

It's easy to see where this could be advantageous for both developers and users. Popular third-party apps will be available to access on the Mac, while presumably new tools will make it easier than ever for developers to port their software to macOS.

But the possibility of iOS apps on the Mac also highlights the areas where continuity between Apple's platforms are lacking, and apps from Apple itself are missing.

Most native apps on an iPhone have equivalent apps on Mac —  Safari, Mail, Notes and Calendar all have mobile and desktop versions. With iOS 11 and the new Files app for iOS, the lines between macOS and iOS have been further blurred.

But the lack of Apple Watch connectivity and support on both Mac and iPad remains an obvious area where Apple's platforms could grow and get better, together.

The addition of LTE connectivity on an Apple Watch gives it more independence from the iPhone, allowing data on the go. Battery constraints prevent it from being a full-fledged, all-day iPhone replacement, but Wi-Fi is abundantly available, and using that instead of LTE allows for much longer uptime with Apple Watch hardware.

Not to mention, sometimes managing apps or viewing data is easier or more convenient on a larger screen. It's easy to see why an Apple Health app for Mac would be preferable to some users, especially those who want to dive deep into the tracking data captured by an Apple Watch or other connected health accessories.

There is also the possibility of enticing new Apple Watch customers who may not be iPhone users. By allowing an Apple Watch to be set up and synced with a Mac instead of an iPhone, Apple's wearable device could potentially expand its reach and attract new users.

Ditching the iPhone entirely might be a stretch, especially considering the fact that notifications on the wrist, via integration with iOS, are a key selling point of the Apple Watch. But regardless, Apple Watch syncing and Health data viewing on a Mac would open the wearable device to new and exciting possibilities, especially as the hardware and battery life continue to improve.

It's a small but significant way that allowing iOS apps on macOS could be a game changer for both platforms, well beyond just letting you play Clash of Clans on your Mac.

No need for the Mac to mimic downgraded Mac apps. And if Apple wants a touch-enhanced Mac, they should make it (and silence their VP's vocalizing that lunatic anti-hybrid attitude)

Other news sources didn’t interpret this as “iOS apps on Mac”, but rather a unified development environment that allows for universal app projects, in the same way as iPhone and iPad apps are universal but quite different implementations — an iPad app is an iPad app, and not just the iPhone app running on an ipad. 

It it has to do with different views (screens) but running the same models (business objects) and class libraries (functions) for easier reuse of your existing code. But the frontends are very different. 

I very much doubt we’re going to be running windowed iOS apps on the Mac as suggested.

I'm not suggesting that the iOS versions of the Watch or Health apps will come to Mac in a windowed mode, as you state. I'm saying that a universal code base version of them could, and that it would be a welcome change for the Apple Watch.

Yup, AI got it wrong In the original, and got quite upset when I pointed it out. 

As you say, this is not running iOS apps on the Mac, which would be a usability nightmare. They’ve aligned the UI frameworks so that it’s much easier for developers to share code between the platforms. It’s also possible that they’re working on a responsive UI, so that it automatically adjusts itself depending on the device it’s running on. 

But no, they’re not going to be running iOS apps on the Mac. Not really their style.

You can run iPhone apps on an iPad, all blown up and ugly if you so choose. Obviously Apple would never do that with its own apps on the Mac, but I could see lazy third-party developers doing half-baked ports of iOS apps, for the sake of having a presence on the Mac.
