My band is snug and properly placed on my wrist. The heart rate indicator is consistently inaccurate during my cardio. This is very frustrating. Just to be sure I double checked with my Apple Watch. My heart rate is generally higher on my Apple Watch. And just to triple check I actually had a pulse oximeter on my finger. This is super frustrating when you’re trying really hard and my heart rate is actually 161. Meanwhile, the WHOOP strap says it’s 129. This is not OK. This is a very expensive product. I expect more what is happening?
