I currently use a coherence and heart-rate monitor from a company called HeartMath. http://store.heartmath.com/innerbalance?_ga=1.197722152.608262048.1457602959
. Its absolutely amazing...
However, this can only be used by tethering the monitor to my ear lobe.
Has anyone come across any watches that can monitor coherence levels? I've looked at Microsoft Band and a few others, but none of them come close to HeartMath.
Any suggestions will be greatly appreciated.
