As an all-in-one health monitoring system, S Health includes the S Band, HRM Band, and Body Scale, transforming your smartphone into a comprehensive health database. You can check your body weight or monitor your heart rate and distance covered during workouts. Each device connects via Bluetooth to the S Health app, transmitting your body analysis data for convenient viewing and management. Adjust the intensity of your training. Whether you're walking, running, or cycling, your smartphone tracks your heart rate and provides real-time data to make your workouts more effective and safer. The highly flexible fabric strap is comfortable and secure, while the waterproof casing keeps moisture away during intense outdoor sessions. Thanks to the latest wireless Bluetooth 4.0 technology used in the HRM Band, you won't have to deal with cumbersome cables and bulky batteries. You also won't have to worry about annoying frequency overlaps. The HRM Band uses a small, replaceable CR2032 lithium battery. With energy-saving Bluetooth 4.0 LE technology, you can train for a year without needing to replace the battery (based on daily use of one hour).
