In addition to some constraints on the type of product (i.e. watch apps have to be focused, super-quick interactions), there's another reason we haven't seen a lot of app, imo:

This year was an unusually crazy year for iOS developers. Apple released: - watchOS 1, with a slow and clunky experience - iOS 9, with adaptive multitasking - watchOS 2, requiring a rewrite of the watch app – tvOS, a whole new platform, with more easily translatable app experiences.

Additionally, with the "2-versions behind" strategy for Xcode, a lot of app developers (myself included) dropped iOS 7 support. This was actually one of the most complex transitions ever. (So many backwards incompatible changes (size classes, presentation controllers, push notifications).)

So something had to give. For me, and for many others, I'd say it was probably the watch.
