Big Difference In Hrv Sense App And Inner Balance App
I've been using a Polar H7 chest strap with the HRV Sense app to monitor my stress levels. What i've noticed is that when I use both. Inner balance with sensor on ipad and polar h7 with hrv sense on iphone. My inner balance will say I'm in high coherence, upper green wth with coherence at ~6/8 but my HRV Sense app will say I'm high in stress :-S.
Does anyone have a logical explanation for this.
