WndWatch enables you to use your watch as a wand. Pretty self-explanatory, really. In the iPhone app, enter a URL to a REST API (e.g. the Webhook trigger on IFTTT). Then, the tap the play button on the watch. This will start the workout session, which will record your watch accelerometer movements. Follow the directions from the phone app to correctly twist your hand, and you should feel haptic feedback indicating that the action has been triggered. Enjoy confusing your friends by simply moving your hand and turning on a light!
