What Modern Recovery Wearables Actually Measure
Modern recovery wearables measure the same handful of underlying signals — heart rate, heart rate variability, skin temperature and sleep stages — then each brand turns that into its own named daily score: Garmin's Body Battery, Oura's Readiness Score, and WHOOP's Recovery Score. Each is a separate, proprietary calculation with its own weighting, so the same night's sleep can produce different-looking scores across devices. We present what each company has actually published about how its own score works — not a claim that the scores are interchangeable or independently validated.
