Here is a smart device that lets you track your kiteboarding sessions on your smartphone conveniently. WOO is a waterproof device the size of a USB stick that tracks your height, airtime, landing g-force, and other data. Just sync it to your smartphone to get detailed reports and the ability to share and compare your results.
The companion app provides you with detailed information about each of your sessions. It also lets you see how you stack up on the WOO leaderboards. This Bluetooth device will be released in August.
