There are actually 4 different types of Apple Watch apps:
1. Glances
2. Actionable notifications
3. Extension WatchKit apps (extension runs on iPhone, view runs on watch)
4. Fully native apps
It appears 1, 2, and 3 will be available for the initial launch, while #4 will be available later next year, probably starting with a beta released at WWDC.
