Oura says 5 hours, your Watch says 7, WHOOP and Garmin disagree on recovery. Sage + Stone reconciles every device into one timeline and shows exactly where they conflict — so you trust the trend, not a single number.
Illustrative app preview
Aggregation isn't reconciliation. Sage + Stone flags when two devices report meaningfully different numbers for the same metric, reads across all of them for patterns no single device can produce, and coaches on the combined picture — including the non-Apple devices Apple Health barely touches. Informational only, not medical advice.
Get Sage + Stone freeApple Health, Oura, Garmin, WHOOP, Polar, Suunto, Strava, Samsung & Google Fit — plus CGM and FHIR lab records — unified via Open Wearables.
The thing no one else does: when your devices disagree on a metric, Sage + Stone shows you both readings and how far apart they are — so you trust the trend.
Correlate HRV with glucose, sleep with training load, recovery with stress — insights that only exist once your devices are in one place.
Baseline drift in resting HR, temperature or HRV — caught across all your devices, days before you'd notice. Informational, not a diagnosis.

Sage + Stone surfaces insights; it doesn't provide medical advice. Talk to your doctor.
