Who should buy which
Endurance athletes, ultra-runners, triathletes, and anyone who needs 2-week battery + serious GPS + training-load science.
You want a smartwatch (go Apple Ultra), you want a passive sleep tracker (go Oura), or you want a coaching strain band (go Whoop).
Buyers who want ring-form tracking without a recurring subscription, especially those starting fresh without Oura's historical data.
You're already on Oura with years of data, or you want the maximally validated sleep-staging accuracy.
