Heart-rate signal missing
Grace continuously tracks your heart rate while you're exercising and throughout the day. If the heart-rate sensor on your watch has difficulty detecting a signal, the green light on the back of the watch will continue to flash continuously.
Next, please make sure you're wearing your watch correctly, either by moving it higher or lower on your wrist or by tightening or loosening the wristband. Grace should be in contact with your skin.
After holding your arm still and straight for a short time, you should see your heart rate again.
If you experience any of the following issues, reset your device:
1. Won't sync;
2. Won't respond to button press;
3. Won't track steps or other data; See "Reset Grace" on how to reset your watch.
