Track Your Moves

Accurate biometric data and performance tracking is the cornerstone of the KuaiFit platform. Using clinically-validated heart rate sensors, KuaiFit precisely monitors your heart rate and calories, and with its in-built accelerometer, tracks your speed, pace, distance, steps, cadence, and laps. It can also measure cadence and power during cycling with an additional cycling sensor.
