Now with this app, you will be able to use Google Glass even with an iOS device. The app lets you screencast your Google Glass screen on to your iOS device, use turn-by-turn navigation and access your contacts and Glassware.
The app is only available on the iPhone but can be installed on the iPad as well. It runs on iOS 7 devices only and requires a data connection and tethering to use turn-by-turn navigation. MyGlass for iOS is available for free on the App Store.
