Marco Arment comments on the terrible state of WatchKit:

Developing Apple Watch apps is extremely frustrating and limited for one big reason: unlike on iOS, Apple doesn’t give app developers access to the same watchOS frameworks that they use on Apple Watch.

Instead, we’re only allowed to use WatchKit, a baby UI framework that would’ve seemed rudimentary to developers even in the 1990s. But unlike the iPhone’s web apps, WatchKit doesn’t appear to be a stopgap — it seems to be Apple’s long-term solution to third-party app development on the Apple Watch.

The Apple Watch may be the best selling smartwatch out there without any competition, but it still has tremendous potential that 3rd party developers aren’t able to make full use of.
