Vert

Forget the traditional forms of jump testing — with the Vert Wearable Jump Device, you can measure every vertical leap you take, whether it's during a training session or in the heat of a game. The sensor itself is a small black affair that's worn around the waist, and can attach to your clothing via the included clip or be hidden inside a specially-designed belt. Using the high-precision gyroscope and accelerometer, it can give you info about your latest flight via the built-in OLED display, but to get the most out of it, you'll want to pair it to your iPhone, iPad, or Android device using the Bluetooth 4.0 connection and use the companion app to track and share a multitude of stats.
