have lost respect for whoop esp b/c almost all of their new release is either misleading with tons of fine print or just a way to extract more $ on unverified/pseudo science eg bp monitoring is "wellness" not medical "diagnostic" b/c they're using ppg on wrist which might be the worst place to do this vs finger, in-ear, arm where arteries are more exposed and not under soft tissue. you should be concerned b/c like US surgeon general, katie holmes has a doctorate in health adjacent to medicine. not surprising, they're all friends

FDA fired a warning shot to WHOOP over the BP feature Osama calls out here https://www.cnbc.com/amp/2025/07/15/whoop-fda-blood-pressure-feature-wearables.html

At this point I am so nihilist and tired, if people want to pay $350 and have freakouts and stress over bad data that’s on them

I’ll take that at least 

I think a big reason I don’t like it is that I feel like there is a higher accuracy burden for reporting a metric like that bc it doesn’t come accompanied with any other symptoms especially when high; silent killer. A BP of 180/120 is an emergency situation and you may not even feel it 

They try to say “oh it’s the same as HRV or respiratory rate” but it’s not. They are true wellness metrics and correlated with how you feel, not silent. A lower fidelity for that number is fine bc trends matter more than absolute values.

With the number of disclaimers whoop has around the feature, and with the pain of setting it up, I don't think anyone reasonable thinks it's a substitute for a real cuff.
