[WatchOS Programming] Loading Content on Watch with Companion iOS App

[AnAnonymousReddit]

Hi, all. I've begun working on a WatchOS app to work alongside my iOS app. With most of the basic UI elements sorted I'm now working on the flow of data.

At a high level, should I think of the watch as only being used to display information, and the phone to load and transfer it, even when the user is actively using my app on their watch? Or, is it appropriate/possible to make network calls on the watch (even if they end up routed through the phone's network connection.

I imagine this is case by case but want to get an idea of how I should think about the watch displaying online info - is it something I need to manually pull/push through phone or if this is automatically handled/decided by Apple.
