MyHealthInsights

MyHealthInsights is a private, on-device dashboard for the health data you already have in Apple Health. It reads your sleep, workouts, VO₂ Max, heart-rate zones, and body composition, then turns them into clear charts and a short, plain-language summary written by Apple Intelligence. Your health data never leaves your iPhone. No accounts. No health data in any cloud we control. This is a reflection app, not a logging app. You enter nothing. The data is already in Apple Health — MyHealthInsights tells you what it means. WHAT YOU GET Insights — On-device AI summary Apple Intelligence reads the last 30 nights of sleep, six months of training, and a year of body composition, then writes a short narrative explaining what's happening. The summary is generated entirely on-device using Apple's Foundation Models framework. A six-up grid of headline numbers gives context. Sleep — last night and the last 30 nights A "Last Night" hero card with Core / REM / Deep duration. A 30-night stacked bar chart of sleep architecture. A trend chart with a 7-day rolling average of total sleep. Plain-language weekly stage averages. Fitness — is your training working? VO₂ Max trend with a tight Y-axis so small fitness changes are visible, and an average reference line. Weekly training volume stacked by heart-rate zone (Z1–Z5) using your real max HR. Per-zone Pearson correlation against VO₂ Max so you can see which zones are moving the needle. Cardio-vs-body-fat and strength-vs-lean-mass correlations for a 28-day trailing window. A workout list with per-row zone distribution. Body — composition over the last year Weight, BMI, body fat percentage, and lean body mass. Each metric gets a card with a directional trend arrow and a per-metric line chart. The layout adapts to whatever you've recorded — if you only have weight, you only see weight. Progress — see your body change Take daily posed selfies — front, side, and back — in a hands-free, voice-guided session: one tap runs a countdown-paced photo burst through every pose. MyHealthInsights stitches each pose into a timelapse video that plays back your transformation, with every frame automatically aligned on your body using on-device Vision so you stay centered across days. An optional daily reminder helps you keep the streak. The photos are saved only on your iPhone — they're never uploaded. PRIVATE BY DESIGN • HealthKit reads happen only on your iPhone. The AI summary uses Apple Intelligence, on-device. • Your processed data syncs to your iPad and Mac through your private iCloud container — managed by Apple, not by us. • Progress photos are saved only in the app's local storage on your iPhone — they are not synced to iCloud and never leave your device. • Your health data and your photos are never collected and never sent to us. The only data that leaves the device is anonymous usage analytics (which tabs you open, Progress actions) via Firebase Analytics — counts and screen names only, never your health data, never your photos. No advertising IDs. • You can revoke HealthKit access from the Health app, or disable iCloud sync at any time. REQUIREMENTS • iPhone running iOS 26 or later. iPad supported (read-only — uses iCloud sync from the iPhone). • HealthKit permissions on the iPhone for sleep, workouts, heart rate, VO₂ Max, body mass family, activity summary, date of birth, and biological sex. • Apple Intelligence-eligible iPhone for the AI summary. On other devices the metric grid still renders and explains why the narrative is unavailable. • Camera access on the iPhone for the Progress tab's posed selfies. Photos are saved only on your device. • Sign in to the same iCloud account on every device for sync to work. • At least a few months of data in Apple Health for the trends and correlations to be meaningful.
