Grappling can be a lot of fun, but you need the right tools and environment to try it. The RollTec Rashguard is a wearable technology made for grapplers. It comes with a motion sensor to help you analyze your training sessions on your iOS or Android device. RollTec tells you which positions you have spent the most time in and suggests how to improve your game.
RollTec gives you a position breakdown by training session, week, month, and year. The sensor connects to your smartphone via Bluetooth. It has a 6-axis sensor with an accelerometer and a gyroscope. RollTec’s algorithm can distinguish between mount, side control, guard, and back control. To get started, put the rashguard on, connect the sensor, start rolling, and review the information on your smartphone. The project is getting funded on Kickstarter.
