Initial Impressions for WatchKit

Today Apple unveiled WatchKit. I am very pleasantly surprised by how capable it is. In my Expectations for WatchKit article I outlined that I thought we’d see a two phase roll-out of the platform. Starting with pretty limited capabilities that would then be expanded at next year’s WWDC. It turns out that I was only half correct. It is two phase but the first phase is much more capable than I was expecting.

In the first phase we will be able to build Glances, Actionable Notifications and iPhone powered apps. The last of which has me most excited.

My only question: how will these apps affect iPhone battery life?
