Meet the RollTec Rashguard: a smart wearable designed specifically for grapplers. It lets you track your rolling positions and improve your game over time. The motion sensor inside the rashguard connects to your smartphone via Bluetooth. The device gives you a breakdown of your positions and suggests how to improve your game.
The RollTec set helps you better analyze your training sessions and suggests technique videos to improve your game. RollTec’s algorithm can distinguish between mount, side control, guard, and back control. The 6-axis combo sensor comes with a rechargeable battery. More information is available on Kickstarter.
