RollTec Smart Rashguard for Grappling

Here is a smart wearable system that helps MMA students and grapplers take their skills to the next level. The RollTec Rashguard has a motion sensor inside that allows you to track your rolling positions and improve your game. RollTec knows which grappling positions you have spent the most time, so it can give you suggestions how to improve.

The device can detect mount, side control, guard, and back control positions. Based on where you spend most of your time, the app suggests technique videos to improve your game. You can use the rashguard whether you train with or without a Gi. Yet another interesting Kickstarter project.
