Health & Fitness
Log blood glucose in seconds on iPhone or Apple Watch, or scan a supported meter's display with the camera. Snap a photo of your meal to estimate its carbs and calories. Your trends, food, and medications sit in one private diary. The app also has reminders, widgets, Apple Health sync, and PDF or CSV reports.
Enter readings on your iPhone or Apple Watch, or point the camera at your glucose meter or scale and confirm the number it picks up. A meal photo gets you a carb and calorie estimate, and the food diary tracks what you eat against your nutrition goals. Widgets put glucose on your Home Screen, Lock Screen, and watch face. You can also turn on Apple Health sync, note stress next to your readings, and export PDF or CSV reports for your doctor.
Your health readings are stored on your device, not on our servers. The app sends a meal photo and any note you add only when you scan that meal, without your name or email. We don't keep the photo or note on our servers. A third-party AI provider does the analysis. It deletes the photo and note within 30 days (the privacy policy lists exceptions) and doesn't use them to train AI models.
Day to Day
Type in the carbs yourself, or snap your plate for an estimated range of carbs, calories, protein, and fat. You can adjust any of it before you save.
Enter the number from your meter, point the camera at the meter's display, or import readings from Apple Health. The reading sits right next to the meal.
Pick any date range to see your trends, then export a PDF or CSV report for your doctor.
Features
Glucose, A1C, blood pressure, weight, insulin, carbs, exercise, ketones, INR, oxygen, and temperature in one diary.
Scan glucose meter and weight scale displays with the iPhone camera, then confirm the detected value before saving.
Snap a photo of your plate to estimate carbs, calories, protein, and fat with honest ranges, within fair-use daily limits.
A food diary that keeps the photos from your meal scans. Check carbs, calories, protein, and fat by day, week, or month, and set your daily goals with the built-in calculator.
Glucose syncs both ways, so CGM readings saved in Apple Health show up in your diary. Weight, blood pressure, insulin, carbs, and more are saved to Apple Health.
Log glucose, weight, blood pressure, insulin, and medication intake from Apple Watch.
Home Screen and Lock Screen widgets for glucose, time in range, and medications, plus a glucose complication for your watch face.

Apple Watch
Log glucose, insulin, blood pressure, weight, and medication doses on Apple Watch (watchOS 11.6 or later). The watch doesn't measure glucose; you turn the Digital Crown to the number on your meter.

Common Questions
No. Your meter or CGM takes the reading, and the app keeps the record. You can type a reading in, point the iPhone camera at your meter's display and confirm the number it picks up, or import readings from Apple Health. Glucose and Blood Sugar Track is a personal tracking tool, not a medical device.
Indirectly, through Apple Health. If your CGM's own app saves glucose readings there, turn on Apple Health sync and they show up in your diary. Some CGM apps share with Apple Health on a delay, so the newest readings can arrive later. The app doesn't connect to sensors directly, and we're not affiliated with Dexcom or Abbott, the maker of FreeStyle Libre. To see where a reading came from, check its source in Apple Health.
Both. You can log glucose in mg/dL, the unit US meters usually show, or in mmol/L, the standard in Canada, the UK, and many other countries. Set the app to match your meter so the number you type is the one on its screen. If you switch meters or bring one home from abroad, check its unit before you log.
Yes. On the watch you can log glucose, insulin, weight, blood pressure, and medication doses, and see your last reading. It doesn't measure glucose: you turn the Digital Crown to the number your meter shows and tap Save. The watch app needs watchOS 11.6 or later, and the iPhone app needs iOS 18 or later.
Yes. Export a PDF or CSV report for the dates you pick, with nutrition alongside your glucose readings. A PDF is easy to print or email, and a CSV opens in a spreadsheet. Before you send it, open the file and check the dates and units. The app sends nothing to your doctor. You decide who gets a copy.
It's available in 32 languages, including English, Spanish, Chinese, Vietnamese, Korean, Arabic, Russian, Hindi, French, German, Japanese, and Portuguese. The app uses your iPhone's language when it's one of them, so a family member who prefers Spanish or Vietnamese sees it in that language on their own phone.

Glucose and Blood Sugar Track is a personal tracking tool, not a medical device. It does not measure blood sugar; it keeps the readings you enter from your meter or import from Apple Health. Always consult your healthcare provider for medical advice, and don't make treatment decisions based solely on this app.
