  • Anyone else finding heart rate measurement VERY erratic ? I have many dropouts to ZERO and spikes way higher than actual. HR graph looks like a pogo stick. Of course , that kills QTc and heart strain numbers. I’m a long term HR athlete wearing a Garmin watch at the same time and seeing normal HR readings there. My Wahoo strap never showed this either.

    • I just got mine yesterday and that’s what I saw! I’m not able to get it to sync to my Garmin and it was a nuisance to have to keep taking my phone out to see my heart rate but the data was useless anyway.

Anyone else having trouble posting issues on the forum?   My strap is erratic with heartbeat (drops out to ZERO during exercise) and registering 30-50% higher than my actual breathing rate (I count and compare to strap).   My heart strain instantly goes to .25 (never anything else) and stays there - always.  My forum posts keep staying "in moderation."   Contact me if you are having issues. I just want this expensive jewelry to work like my other HRMS do!
