The Green Lion Fit Wear Smart Fitness Band functions as a multipurpose fitness tracking device, which enables users to monitor their health and fitness activities. The band features a nylon wristband, which provides both comfort and extended wearability. The device uses advanced sensors, which include the HX 3697 heart rate sensor and 6-Axis ST LSM6DSOETR3 motion tracking system to deliver accurate health and fitness measurements that track heart rate patterns, sleep cycles, stress levels, and SpO₂ values. The band provides HRV analysis, which enables users to monitor their fitness levels more effectively. The device uses Bluetooth V6.0 BLE to establish connections with iOS 9.0 or later and Android 5.1 or later devices, which enables users to control apps and receive call notifications. The 110mAh battery provides operational capabilities that last between 7 and 10 days, while the 5ATM waterproof rating enables you to use it during swimming activities. You can keep this fitness band ready for your next workout because it charges quickly within one hour.
