Food Diary, Calories & Macros

Only for iPhone

Free · In‑App Purchases

iPhone

What did you eat? How did your glucose change? Snap a photo, let AI analyze nutrition, and compare post-meal glucose to find what works for you. Keep a photo food journal with estimated calories, macros and fiber. Record glucose readings and A1C lab results, then review your records over time. PHOTO MEAL JOURNAL Take or choose a meal photo to receive AI-generated estimates of calories, carbohydrates, protein, fat and fiber. Add notes about ingredients, portions or preparation. Open About this meal to see foods and amounts as an easy-to-read list, along with details that are less certain. GLUCOSE AND ACTIVITY Log glucose readings or choose to read available glucose data from Apple Health. Separate Glucose and Activity controls let you choose what to connect. Activity includes steps and Walking + Running Distance. Imported readings retain their original sample time; if no data is available, no entry is added. A1C RESULTS AND HISTORY Enter an A1C result from your lab report in % or mmol/mol and save the test date. View your results in a chart and dated list. A1C units are separate from the mg/dL or mmol/L units used for glucose readings. GluNudge does not calculate A1C from your glucose log. OPTIONAL ICLOUD SYNC Turn on iCloud sync to keep A1C records, edits and deletions in sync across devices signed in to the same iCloud and GluNudge accounts. Existing local A1C records are included when sync is enabled. A1C does not connect to Apple Health. REVIEW YOUR RECORDS Explore daily nutrition trends and weekly, monthly, three-month and yearly reports. Use the calendar to revisit meals and glucose readings by date. Create Meal Recaps to save or share. GluNudge helps you observe your records without treating estimated nutrition as a measured glucose response. YOUR CHOICE Apple Health access is optional. Imported Apple Health glucose and activity data stay on your device. When you request cloud meal analysis, the selected photo and relevant meal context are processed by our service and AI providers. See our privacy policy for details. Some AI features require an account and an active GluNudge Plus subscription or available trial. Subscription terms and pricing are shown before purchase. GluNudge is for general wellness and journaling. It does not measure or predict glucose, diagnose or treat conditions, or provide medical advice. Nutrition estimates may be inaccurate. A1C reference bands are not a diagnosis or a personal treatment target. Privacy Policy: https://glunudge.app/privacy/ Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

  • This app hasn’t received enough ratings or reviews to display an overview.

• Now supports iPhone Duo with a two-column layout when unfolded. Browse your overview while opening meal details, nutrition trends, A1C history and settings on the right. • Keep meal and A1C drafts as you fold, unfold or rotate your device. Scroll each pane independently. • Tap Done to dismiss the keyboard without saving or losing your meal notes, on iPhone and iPhone Duo. • Timeline cards now show steps since the previous record, with the time range. The first record starts at midnight; daily totals stay in the daily summary. Missing step data stays hidden. • Fixed Chinese step counts and units wrapping awkwardly on narrow screens.
