The Android Wear app that Hyundai demonstrated at CES several weeks ago is now available on Google Play, letting owners of appropriately-equipped models control their cars from their wrists. The app is basically a scaled-down version of the Blue Link app already available for Android phones — you can start and stop the engine, lock and unlock the doors, find the car if you can't remember where you parked it, and flash the lights, among other things. The app also supports voice controls, so you can just say things like "find my car" instead of tapping through the UI.
Any car with first- or second-generation Blue Link is supported, starting with the 2012 Sonata. In addition to Android Wear support, Hyundai notes that an Apple Watch version will be available "shortly after its release."
