- 📦Correlate - Health Insights updated to version 2.7.0Correlate 2.7 connects to your Oura account, so your Oura scores arrive on their own — no more CSV exports.
NEW
• Connect Oura. In Data Sources, connect your Oura account once and Correlate syncs a year of readiness, sleep and activity scores, temperature deviation, nightly HRV and daily stress, then keeps them up to date when you open the app. Requires an active Oura Membership. They sit next to your Apple Health data in the Lab and Deep Dive.
• Already imported an Oura CSV? Synced days extend that history instead of starting a second copy.
PRIVACY
• Read-only: Correlate never changes anything in Oura and never writes Oura data to Apple Health. Your Oura data goes from Oura straight to your iPhone.
• Disconnect any time, and choose whether to keep or delete the Oura data in Correlate.
FIXED
• Swiping to delete an imported series no longer closes the app.… more - 📈Correlate - Health Insights entered the top 100Top Paid · Health & Fitness · JP

- 📦Correlate - Health Insights updated to version 2.6.0Correlate 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.

Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum

faster than 0% of Health & Fitness apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About Correlate - Health Insights
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
• Connect your Oura account (Oura Membership required) to sync readiness, sleep and activity scores automatically — read-only, straight to your iPhone
• Or import Oura and WHOOP official exports, parsed entirely on-device
• 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.
