Dawn Phenomenon

About Dawn Phenomenon

The biggest update since 1.0. — ON-DEVICE AI COACH (Apple Intelligence) — Tap "Ask Coach" on any night and ask whatever you want — "did I have dawn phenomenon last night?", "which tags push my rise higher?", "what changed this week?" The Coach is grounded in your actual data and runs entirely on your iPhone using the Apple Intelligence Foundation Models framework. Nothing leaves your device. — PER-NIGHT JOURNALING WITH AUTO-TAGS — Tag any night with context (late dinner, alcohol, illness, evening exercise, missed dose, and more). Trends now show how each tag affects your overnight rise — e.g. "Late dinners: +18 mg/dL." When you open the journal, we suggest tags automatically based on the workouts, carbohydrates, and alcohol you've already logged in Apple Health. One tap to accept. — APPLE WATCH APP — Glance at last night's classification and rise from your wrist. Pull to refresh. — LOCK-SCREEN + HOME-SCREEN WIDGETS — "Last Night" shows yesterday's classification + rise. "Dawn Score" shows the percentage of analyzable nights with a dawn pattern over the last 7 days — circular for the lock screen, plus a small home-screen variant. — RICH MORNING NOTIFICATIONS — Background fetch quietly analyzes last night and pushes a content-rich notification ("Dawn phenomenon last night — glucose rose +52 mg/dL"). Toggle in Settings → Notifications. — SLEEP DURATION ↔ DAWN RISE CORRELATION — A new scatter chart on Trends shows sleep hours vs. rise size. Does less sleep make your morning rise worse? Now you can see it. — PER-NIGHT PDF REPORT — Share a single-night report (curve, classification, time-in-range, details) from any Today page, alongside the existing multi-week PDF. — MEDICAL REFERENCES — Every clinical threshold and classification now cites the peer-reviewed and consensus source behind it. References are one tap away from every screen. — CONFIGURABLE THRESHOLDS — Tune the rise and hypo thresholds in Settings to match your own targets. Reclassifies instantly. — iCLOUD SETTINGS SYNC — Bed and wake times, thresholds, and journal preferences now carry between your iPhone and iPad via iCloud key-value storage. — FIXES & POLISH — • Sleep window now uses the longest sleep session per night, handling both Apple Watch fine-grained stages and inBed-only data • Better empty-state guidance when your CGM hasn't written data yet • "Open Settings" recovery if Health permission was denied • VoiceOver labels on the chart, donut, and Dawn Score gauge • iPad layout cleanup • Haptic feedback on swipe through days and dawn detection • Dawn-themed launch screen and app icon All processing still happens on your device. No accounts. No analytics. No third-party SDKs. Important — Dawn Phenomenon is for informational and educational purposes only.
