Questions
WHOOP or Oura for training?
WHOOP is built around training strain and recovery; Oura around sleep. WHOOP costs $398 over two years on One with the strap included. Oura Ring 5 costs about $539 over two years and read overnight HRV closer to ECG in a 2025 study of earlier models.
Do I need a recovery tracker with a screen?
No. WHOOP and smart rings have no screen, and all data lives in the app. If you want time and notifications on your wrist, the Withings ScanWatch 2 adds analog hands and a small display, with up to 35 days of battery, per Withings.
