Dawn Phenomenon analyzes your overnight glucose data and shows the patterns most people never see — when your sugar bottoms out, when it starts rising, and whether last night fits the classic "dawn phenomenon" pattern. • Reads your CGM glucose readings and sleep window from Apple Health • Great for users of a GLP-1 • Detects the dawn phenomenon (overnight low to morning rise of 30+ mg/dL by default) • Differentiates dawn phenomenon from the Somogyi effect (a rebound after an overnight hypo) • Shows last night with an interactive curve, nadir, peak, waking reading, and time-in-range • Swipe to revisit the last 5 nights • Trends tab overlays your week, shows a "dawn score" (how often dawn pattern appears), the average rise, and how sleep duration correlates with rise size • Export a PDF report of any single night or your full week to share with your endocrinologist **Privacy first** All analysis happens on your device. Your glucose and sleep data never leave it. No accounts. No third-party services. Settings sync via iCloud key-value storage only. **Customize the analysis** Tune the rise and hypo thresholds in Settings to match your own targets. Choose whether to pull bed/wake times from Apple Health's sleep samples, or set them manually. **Important** This app is for informational and educational purposes only.
