I am developing a simple standalone app for the Apple Watch. I really don't need any functionality on the phone. Am I required to provide an iPhone app?

The watchkit documentation is something like:

Create WatchKit apps. WatchKit apps have two parts: A WatchKit extension that runs on iPhone and a set of user interface resources that are installed on Apple Watch. When your app is launched on Apple Watch, the WatchKit extension on iPhone runs in the background to update the user interface and respond to user interactions. WatchKit provides three opportunities to extend your iPhone app to Apple Watch: WatchKit apps, Glances, and actionable notifications.


Yes, a corresponding iOS app is required. The watchOS component is considered an extension by Apple and not a standalone product.

See Preparing Your App Submission for Apple Watch:

App Review

All iPhone apps with a WatchKit extension submitted to the App Store are reviewed based on a set of technical, content, and design criteria. Make sure to use our guidelines and resources before submitting your app for review.
