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.

Requires an iPhone with Apple Health data. An Apple Watch is recommended for recovery, strain, heart-rate and sleep metrics.
Quoi de neuf dans la dernière version ?
A sharper, more consistent look — and a Weekly Digest that gets to the point.
• A refreshed design language: one accent system across every screen — green for your body, blue for actions — with unified cards, cleaner typography, and color-coded metric categories in Deep Dive.
• Correlator, refined: the X and Y axis pickers now carry the app's signature colors, and the date range (7 days to 1 year) moved out of a hidden menu into one-tap chips right above the chart.
• Weekly Digest, redesigned: it now opens with the conclusion — how many metrics improved, what needs attention — with week-over-week comparison bars for every metric.
• Fairer trend colors: improvements are judged by what's actually good for each metric. A falling resting heart rate now correctly shows as progress, not decline.
• Under the hood: cleanup and stability improvements.
All on-device, all included in the one-time purchase — no subscription, ever.
