Hello folks, I'm really looking forward to the Apple watch as a category of device which will again change the world of computing. Details have come out regarding the SDK and various editions but still not sure what the device can do owing to the fact that it has a unique hardware with several new sensors. I'm making this thread for all to explore and learn from the community what the device can do. 1. Is the Apple watch aware when I'm still certain distance off the ground? Can it measure the precise time and distance off the ground? I know it has a barometer. 2. Can the watch persist data if it's not within the vicinity of the paired iPhone? What else ... feel free to add.
