Using the sensors available in the Microsoft Band, Sound Band lets you activate sound effects through motion. This is the initial release, and—currently—the only available sound is "whip," which lets you simulate cracking a whip without all of the drudgery of actually having to buy and learn how to use one. To come: Improvements on whip-like motion detection, more sound options. Potentially to come: Improvements to speed of connection between the app and the Band. Currently: The trial is an ad-supported full version of the app, but this is subject to change. Improvement to whip motion detection. Added a "Give Feedback" button to the Settings page.
