Meet the Kenzen ECHO H2: a wearable device that helps you wirelessly monitor your lactic acid and calories. The smart patch relies on a drop of sweat for real-time analysis. It alerts you to adjust your workouts on your smartphone. In addition to hydration, lactic acid and glucose monitoring, the ECHO H2 tracks speed, active heart rate, and 3D motion.
The ECHO H2 measures heart rate, variability, calorie intake, and skin temperature. You can use the companion app to get useful reports (e.g. humidity), capture posture and 3D motion, and track speed, acceleration, and speed. You can find the product on Indiegogo.
