We will build a good app for iOS, but be prepared - there is no way for us to support all the functionality that Apple Watch has access to. Apple closed off the ability of smartwatches after Pebble to negotiate with carriers to provide messaging services, and now requires users to turn off iMessage (disabling iOS’s core messaging platform) if they want to take advantage of such contracts between a third-party smartwatch maker and cellular carriers. Well, mostly because Apple systematically makes it nearly impossible for 3rd party wearable developers to build a smartwatch experience comparable to Apple Watch experience.
