Meet the VERT: a smart wearable device that monitors and reports your jump data. This jump rate monitor provides you with a non-invasive way to track your performance. It pairs with an iOS app, allowing coaches to monitor it during use. It reports jump rate, jump height, and other jump-related measurements. The VERT device can calculate motion in all directions and relies on a a proprietary algorithm to measure vertical height.
The device is compact and discreet. It will set you back under $125. The companion app is available for free. The VERTcoach app, which helps coaches get more out of their players, is a paid app though.
