CarbTrack vs Dawn Phenomenon

CarbTrack goes beyond basic CGM charts by adding the missing context: what you ate, estimated carbs/macros, meal timing, and patterns over time. Your CGM shows the line — CarbTrack helps explain why it moved, which meals tend to work best for you, and what to watch for next time. Whether you have Type 1, Type 2, or Gestational diabetes, CarbTrack adapts to your goals and your routine. KEY FEATURES AI Photo Carb Detection — Snap a photo of any meal and get estimated carbohydrates and macros with confidence scores. Quickly adjust or log custom foods when you need to. Blood Sugar Logging & Trends — Log readings your way (fasting, pre/post-meal, bedtime, CGM) and view daily summaries, trend views, and weekly insight cards that connect meals to real glucose outcomes. Insights that go beyond CGM — CarbTrack pairs food + timing with your glucose curve to surface patterns like repeat "spike meals," delayed responses, and what meal types tend to lead to steadier results for you. Smart Alerts — Get warnings for high-fat or high-protein meals that may delay glucose spikes (the "Pizza Effect"). Customize thresholds and notifications to match your body and your schedule. CGM Integration — Sync readings from Dexcom (G6/G7) or LibreView (FreeStyle Libre) automatically and see meal data alongside glucose response for faster pattern recognition. Community Chat & Meal Sharing — Join rooms with others managing diabetes. Share meals, swap tips, and stay motivated with people who get it. WHY CARBTRACK? Most nutrition apps weren't built for diabetes — and most CGM apps don't include meal context. CarbTrack brings them together: AI meal estimates, glucose trends, and meaningful analysis so you can learn what works for you, meal by meal. CarbTrack provides educational insights and is not a medical device. Always follow your clinician's guidance for treatment decisions. Works with Dexcom G6/G7 and FreeStyle Libre CGM cloud data. These systems have regulatory clearance in the United States, European Union, Japan, Canada, Australia, and additional regions.

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.
