Do you need to track your heart rate and blood oxygen level? There is the app for it. Check your oxygen saturation and heart rate anytime, anywhere with the Health & Fitness Track Manager at your home or office - when you wake up, relax, before and after exercise. App used an advanced algorithm to calculate oxygen saturation from the sensor's raw infrared and red signal output, similar to how a dedicated pulse oximeter works. Disclaimer: App measurements are just recommendations and can’t be used for diagnostics or medical purpose. Always seek a doctor's advice before making any medical decisions.
