Blood Sugar: Glucose Monitor

Blood Sugar is the diabetes app for tracking blood sugar, carbs, insulin and HbA1c — with an AI meal scanner that counts the carbohydrates from a photo of your plate.

More time in range means more energy, better days, and fewer long-term complications. Blood Sugar shows you exactly what puts you there: every reading, every meal, and the connection between them.

EVERYTHING IN ONE PLACE
• Log blood sugar in seconds — by hand, by voice, or straight from your sensor
• CGM and meter readings flow in automatically through Apple Health
• Track insulin doses, medication, carbs, weight, ketones and steps
• Readings, doses and carbs sync back to Apple Health, both ways

SNAP YOUR PLATE, GET THE CARBS
• Photograph any meal and AI names the food and counts the carbohydrates
• Scan barcodes and nutrition labels the same way
• Search Open Food Facts and USDA FoodData Central — millions of foods with carbs per portion
• Every food you scan joins your own library with its photo, one tap away next time

SEE WHAT EACH MEAL DOES TO YOU
• Log the meal, then the reading two hours later — the before-and-after pair clinics ask for
• Every meal keeps its own result, so the foods that spike you stop being a guess
• Beautiful charts show your day, week, month and year at a glance

TIME IN RANGE, THE WAY YOUR CLINIC MEASURES IT
• Target ranges preset from the International Consensus figures for type 1, type 2 and pregnancy
• See the share of every day, week or month spent in range, low and high
• mmol/L or mg/dL — whichever your clinic uses

HbA1c AND LAB RESULTS
• Watch your estimated HbA1c move between appointments
• Enter what the lab reported and compare it with the estimate side by side
• Keep cholesterol, triglycerides, kidney markers, thyroid and vitamin D in the same place

A REPORT YOUR DOCTOR WILL ACTUALLY READ
• A printable PDF of any period, in any language
• Averages first, then every reading, meal and dose day by day
• Email it before the appointment or hand it over at the desk

REMINDERS THAT FIT YOUR DAY
• A check before breakfast, one after dinner — at the hours you actually keep
• Medication reminders, tests to book, supplies to reorder
• Log with Siri, from the Home Screen or from Control Centre

BUILT FOR EVERY TYPE
Type 1, type 2, gestational diabetes and prediabetes. A few questions at the start set your range, your units and the tiles you see — nothing you do not use gets in the way.

FREE, WITH PLUS FOR MORE
Logging is free and stays free: readings, doses, meals, weight, ketones, reminders, charts and Apple Health. Plus adds the AI meal scanner, the food database, photos on your foods, and the doctor's report.

PRIVATE BY DESIGN
No account, no sign-up. Your health data stays on your device and syncs through your own private iCloud, where we cannot see it. Food photos are analysed and discarded, never stored.

ADDITIONAL FEATURES
• Full data export and backup
• Home Screen and Control Centre shortcuts
• Apple Health two-way sync
• Dark mode support
