Keep Your Head in the Game
Tracking your emotions can help you spot things that knock you off your game.
The Amazfit Helio Ring monitors physical indicators of emotional states with its electrodermal activity (EDA) sensor, and combines that with your heart rate variability (HRV) to detect changes in your daily and weekly expression of emotions.
In the Zepp App, log whether the detected emotion accurately matches how you're feeling. The more you log, the more accurately your summary will reflect your emotional state.
Note: This function needs to be installed via software update. Auto Emotion Monitoring needs to be enabled in the Zepp App, and may result in shorter battery life.

Keep Your Finger on the Pulse of Health
As a smart wearable worn on the finger, the Amazfit Helio Ring can read your pulse clearer for even more accurate⁷ heart rate, blood-oxygen and stress tracking.
As a result, you'll have an even clearer picture of your mental and physical recovery. It's an elite health tracker for elite athletes.
Measurement Methods
-
Cut a strip of paper long enough to fit around your index finger.
-
Wrap the paper around the finger for a natural fit, not too tight. Aim for a comfortable yet snug fit.
-
Use a pen to mark the point where the paper overlaps.
-
Straighten the paper strip and measure the length from tip to pencil mark. The result is your ring size measurement.
-
Wrap a piece of thin string around the widest part of your index finger - avoid using string that's made from overly stretchy material.
-
Wrap the string around the finger, keeping it snug but not too tight. Make a mark with a pen where the ends of the string overlap.
-
Lay the string flat, then use a ruler to measure from one end of the string to the marked point.
-
Compare this measurement with the ring size chart to find the corresponding size.
