Correlate 2.5 is a new Dashboard, and it works in light mode. • Recovery, Strain and Sleep lead the page as three rings, with the morning verdict and your HRV right under them. • Vitals — respiratory rate, resting heart rate, HRV, SpO2, wrist temperature and sleep — each checked against your own recent range, so "Normal" means normal for you. • Strain is rebuilt from your heart rate minute by minute, so a hard session counts as one. Workouts show up in the Strain detail with their source. • Every score is now a tile: Body & Recovery, Zone 2, workouts, sleep consistency, sleep debt and everything that used to live under More. Tap any tile for the full detail. • A month calendar of daily Recovery, Strain and Sleep scores, from the calendar button on the Dashboard. • Light mode. Correlate follows your iPhone, or pick Light or Dark under Data Sources › Appearance. • The daily journal is its own tab, and it explains at the bottom how your answers feed the correlation analysis. • Your verdict appears from day one, computed from the Apple Health history you already have; the 14-day countdown only applies to your first correlation report. • A shorter first launch: connect Apple Health, optionally pick what you want to figure out, done. • Mood, food, hydration and symptom logging have left the Dashboard. Existing entries are untouched. • Data Sources › Privacy: a switch to turn off anonymous usage statistics. Your health data never leaves your iPhone either way.

Sleep fixes, prompted by a reader who noticed Correlate had stopped seeing their sleep stages. • If two apps write sleep for the same night, the one that recorded your stages now wins. Before, a sleep app logging one long "asleep" block could out-rank your watch's REM, deep and core — and the night showed as 100% Core with a quality score stuck at 45. • Bedtime and wake time now come from the same source and the same night. Falling asleep before midnight no longer produces a phantom late-evening "wake", and an afternoon nap no longer stands in for bedtime — so Sleep Consistency and your circadian profile read your actual schedule. • Sleep Consistency no longer drops to zero over a single odd night. A red-eye or a sick-day catch-up sleep is left out of the spread, and the card says when that happened.

A clearer journey: pick your questions, build a 14-day baseline, get your first real discovery. • New onboarding: choose 2–3 questions you want answered — your picks decide what the daily journal asks. Health access is requested only when you start, and never before you know why. • New Today tab: one verdict, one action, and the 20-second journal — answerable inline, with a one-tap "mark remaining as No". Cards appear only when they have something to say. • Honest first 14 days: instead of premature insights, Today counts down to your first correlation report — because a pattern needs enough days to be worth trusting. • Your first discovery, celebrated properly: a full-screen moment with the evidence (r, sample size, significance) and a share button. Clearly labeled: correlation, not causation. • Simpler navigation: four tabs. Coach now lives in Discover as the "Ask your data" entry; Correlate and Deep Dive merged into Lab. • Removed the Sunday wrap-up popup (a better version will return). • Environment now shows only what can be measured — UV, temperature and humidity. Air quality and pollen are gone: there was no source for them on your device, so they should never have been on screen, and no insight is built on them any more. • Workout readiness charts the days you actually recorded, rather than a generated week. • If Health access is off, the app says so and offers a way to fix it, instead of leaving you with empty rings. • Sharing a discovery now carries its name with it, so it arrives titled in Messages, Mail and AirDrop. • Fixed a crash when asking whether something changed, on a yes/no habit you had not logged yet. • A strong negative correlation no longer reads as good news: the discoveries list and the share card now colour direction the way the result badge always did.

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.

A daily habit journal, answers in your own words, and a brand-new look. • Daily Journal: track habits like alcohol, caffeine, workouts, or screen time with quick Yes/No check-ins — editable presets plus your own custom habits, with back-fill for the last two weeks. Every answer feeds straight into your correlations, the With vs. Without card, Coach insights, Discover, and your weekly digest. • Ask Your Data: tap a question — "Does one thing affect another?", "What affects my sleep?", "Did something change recently?" — and Correlate builds the analysis for you: verdict in plain language, the numbers behind it, and an honest note when there isn't enough data yet. You can also just type the question in your own words. • Coach answers, restructured: every answer now shows Your Data (with the exact figures), What Science Says, and Try This — so you always see why a suggestion was made. • Habit insights: once you've logged a habit for 5+ days each way, Correlate shows how your recovery, sleep, HRV, or steps really differ on those days — effect sizes included, honestly labeled as patterns, not proof. • A new icon and a sharper look: the X × Y mark, a unified accent color, and full support for iOS dark and tinted icon styles. • Fairer scores: an ordinary day now reads as a good day. We recalibrated Health Score and sleep quality around your personal baseline, stopped punishing brief nighttime stirrings the watch over-counts, and added a percentile line so you always know what your number means. All on-device, all included in the one-time purchase — no subscription, ever.

Your wearable's scores, correlated — and insights that find you. • Import your Oura & WHOOP data (Oura Trends CSV, or the WHOOP export .zip as-is — no unzipping). Recovery, Readiness, Day Strain, HRV, skin temperature and more line up right next to your Apple Health metrics. Parsed 100% on your iPhone. • Correlate anything against anything: imported scores work on either axis, in Auto-Discover, the correlation matrix, causality, and Deep Dive. • See what your habits actually do: import your WHOOP journal and a With vs. Without card compares your recovery, sleep, or HRV on the days you did vs. didn't — you can even highlight those days right on the scatter chart. • Delayed effects, caught: Correlate quietly scans delays of up to a week and offers a one-tap suggestion when a lag tells a stronger story. • New Sleep Consistency score — how steady your bed and wake times are — on the Dashboard, the Sleep view, Discover, and your weekly digest. • Coach now spots behavior patterns for you, honestly labeled as patterns, not proof. • Export Everything: your whole history — every metric and imported series — in one CSV. • Optional new-discovery alerts (off by default, computed entirely on-device). • Charts explain themselves with a tap, trends scrub back through past days, and significance labels are now backed by exact statistics. Thanks for using Correlate!

• Slide to inspect — drag your finger across any trend chart to read the exact value and date at each point. Now on every chart in the app. • More accurate sleep duration — if you use more than one sleep tracker, or sleep past midnight and into the morning, Correlate now picks your most complete source for each night and counts the full night. Totals that looked too low are now correct. Thanks for using Correlate!

1. Smarter Correlations The Correlator now goes beyond simple correlation. Granger Causality Analysis reveals which metric actually drives which — see if poor sleep causes low HRV, or if it's the other way around, with lag detection up to 7 days. No more guessing which metrics to compare. Auto-Discover scans all your data and surfaces the top 5 strongest correlations automatically. Just tap any discovery to explore it. 2. Deep Dive Upgrades Natural language insights now appear at the top of every metric's statistics view, telling you what the numbers mean in plain English — like "Your latest Steps is 15% above your average — great." Star your most-used metrics for quick access. Favorites appear at the top of the Deep Dive list so you can skip the scrolling. Swipe any metric to add or remove it. 3. Personal Records Track your all-time bests across 9 key health metrics. See when you set each record, and get alerts when you're within striking distance of beating one. 4. CSV Data Export Export any metric's data as a CSV file directly from the Deep Dive detail view. Share with your doctor or analyze in a spreadsheet — your data, your way. 5. Quick Actions Long-press the app icon to jump straight to Correlate, Deep Dive, or Discover — no need to open the app and navigate. 6. Under the Hood Major architecture refactoring for improved stability and faster data loading. Consolidated shared types, split large services into focused modules, and enabled dependency injection across all view models for better reliability. Improved stability and performance across the app. Enhanced data analysis accuracy for health metric correlations. Bug fixes and minor UI improvements.
