Sep 28, 2026
New version 2.5.0 → 2.6.0

Correlate 2.6 brings the mood you log in Apple Health into your correlations, makes the journal easier to keep, and gets your age right. NEW • Mood from Apple Health. Log your mood in the Health app (State of Mind) and Correlate turns it into one daily value you can correlate with sleep, recovery, strain or any habit in the Lab. A Mood tile appears on the Dashboard while you have recent entries, and reads your mood as a word — "Slightly Pleasant", not a number. • Fill in yesterday. If yesterday's journal isn't finished, the Journal tab opens on it first, with a Skip button. • Contact / Report a Problem, in Data Sources › About, emails us with your app and iOS version attached. No health data is included. IMPROVED • Biological Age now uses the date of birth and sex from Apple Health, so your calendar age, heart-rate zones and strain reflect your real age. You can also set them under Biological Age › Edit Profile. • "Pace of Aging" is replaced by a 30-day change that only calls a trend when it is clear. • Training load balance waits until it has enough days of data before giving a verdict. • Wrist temperature shows up on the morning you wake, not a day behind. • Tapping a reminder opens the tab it's about. • VoiceOver: on the Journal tab, swipe up or down on the date to move between days. PRIVACY • Delete All App Data now removes everything Correlate stores on your iPhone and takes you back to setup. Your Apple Health data is never touched. • In the EU, UK and Switzerland, usage statistics stay off until you turn them on in Data Sources › Privacy. Correlate now requires iOS 18 or later.

About

Recovery. Strain. Sleep. Readiness — from the Apple Watch you already wear. Correlate turns your Apple Health data into the daily recovery, strain and sleep scores you'd expect from a dedicated fitness band or smart ring — with no extra hardware to buy, no monthly subscription, and your health data never leaving your iPhone. ◈ YOUR DAILY READINESS One verdict each morning: push today, or back off and recover. • Recovery, Strain & Sleep — three scores, one glance • Health Score that shows what went into it • Stress Load, daily energy, HRV resilience & Biological Age • Sleep stages (REM, Deep, Core), sleep debt and consistency ◈ ALREADY WEAR A RING OR A STRAP? BRING IT ALL TOGETHER • Import your Oura and WHOOP official exports — parsed entirely on-device, no account linking • Garmin and other watches that sync to Apple Health are picked up automatically • One place for every source and every score, and your history stays yours if you ever cancel a membership ◈ FIND WHAT ACTUALLY MOVES YOUR NUMBERS Does late caffeine wreck your sleep? Does a hard run lift tomorrow's HRV? • A 20-second daily journal: a few yes/no questions you chose • With vs. Without: how your recovery really looked on days you did a habit vs. days you didn't • Auto-Discovery scans for real correlations (Pearson r), including delayed effects up to 7 days out — labeled as patterns, never as proof ◈ BUILT FOR PEOPLE WHO READ THE NUMBERS • Pro-grade stats: median, standard deviation, variability, trends and outliers • Dual-axis charts and scatter plots you can interrogate • A plain-English coach that shows its work, generated on your iPhone ◈ NO SUBSCRIPTION. NO NEW WEARABLE. TOTAL PRIVACY. • One-time purchase — no monthly fees, ever • Works with the Apple Watch and iPhone you already own • 100% on-device analysis — no account, and your health data never leaves your phone. Usage statistics can be turned off in settings. Stop renting your health insights. Own them. Requires an iPhone with Apple Health data. An Apple Watch is recommended for recovery, strain, heart-rate and sleep metrics.
