Do you use WHOOP, Oura, or just Apple Watch? Why?

I'm curious about this community's setup. I pay for WHOOP ($239/year) but realized my Apple Watch already collects most of the same raw data

  • HRV, resting heart rate,

  • sleep stages,

  • blood oxygen.

What I was actually paying for was the analysis layer (strain score, recovery, sleep coaching), not the hardware.

Are you using WHOOP, Oura, Garmin, or just Apple Watch?
