What's the new stuff of S-Health application in Samsung Galaxy Note4(SM-N910)?

The latest version of S Health on the Samsung Galaxy Note 4 comes with all the capabilities and features. An exercise tracker with built-in pedometer, and the ability to keep tabs on food, weight, sleep patterns (with a supported accessory), and your heart rate using the built-in sensor.

On top of that, the phone can now sense your blood oxygen saturation (SpO₂) and the strength of ultraviolet light from the sun. Both of these are measured using the Note 4's sensor module, which is once again situated below its rear camera.
