Correlate - Health Insights

iPhone / Forme et santé

Recovery. Strain. Sleep. Readiness — from the Apple Watch you already wear.

Correlate turns your Apple Health data into the daily readiness, recovery, and strain scores you'd expect from a dedicated fitness band or smart ring — with no extra hardware to buy, no monthly subscription, and nothing ever leaving your iPhone.

If you've wanted a recovery wearable but not the price tag or the never-ending membership fees, your Apple Watch already captures what you need. Correlate does the rest.
