The Diabetes Tracker App That Puts Blood Sugar Next to What You Eat
- 10 Minute Read
Blood glucose, carbs, insulin, medications, and meals in one view for type 1 diabetes, type 2 diabetes, gestational diabetes, and prediabetes. Already use MyNetDiary? Turn on BG & Diabetes Tracking in Settings.
MyNetDiary is a diabetes tracker app built into a free calorie counter with 32 million registered users. You log blood glucose with context labels, count carbs against a staff-verified database of 2M+ foods, and record insulin and medications. BG Patterns then lines up each reading with the meals, doses, and exercise from the same part of the day, so recurring patterns are easier to see.
Food and carb logging are free, with no ads and no account required to start. The BG & Diabetes Tracking module comes with Premium.
How diabetes tracking works in MyNetDiary
- Turn it on. In Settings, switch on BG & Diabetes Tracking and choose your diabetes type: Pre-Diabetes, Type 1, Type 2, or Gestational. Insulin tracking has its own toggle.
- Set your target ranges. Open BG Targets and enter the ranges your diabetes care team gave you for fasting, before-meal, after-meal, and bedtime readings. The starting values are software defaults, not recommendations, so replace them with your own.
- Log readings with labels. Enter each blood glucose value with a label such as Fasting, Before breakfast, or 2h after lunch. Turn on After Meal Reminder Prompts and the follow-up check reminder is created for you when you log a meal.
- Review and share. Check BG Patterns daily or weekly, then print, export, or email the report to your doctor, dietitian, or diabetes educator.

How does blood glucose tracking work in MyNetDiary?
You log each reading with the time, the value in mg/dL or mmol/L, optional notes, and one or more labels. The app compares the reading with the target range assigned to that label and highlights it, yellow when it is above range and red when it is below. Daily, before-meal, and after-meal averages appear at the top of the Dashboard.
Labels and target ranges
Built-in labels cover Fasting, Before and After each meal, 2h after a meal, Before bed, Night, activity, and symptoms, and you can add your own. BG Targets holds an editable range for each group of labels. Targets vary by diabetes type, pregnancy, treatment, and individual circumstances, so the starting values are defaults rather than medical recommendations.
Meter and CGM readings through Apple Health and Health Connect
Blood glucose syncs both ways with Apple Health on iPhone and Health Connect on Android. Readings that your meter or continuous glucose monitor app shares there appear in MyNetDiary, and your entries are written back. There is no direct connection to meters or sensors. The app shows both kinds of reading as BG, although a meter measures glucose in blood and a CGM measures it in interstitial fluid.
What is BG Patterns?
BG Patterns divides each day into seven time slots and places your blood glucose readings, color-coded against your ranges, next to the meal carbs, insulin, medications, exercise, and notes logged in the same slot. It is a review tool for spotting recurring patterns to discuss with your care team, not a diagnosis of why any single reading was high or low.
What a row looks like
Take a dinner row, with example numbers. It shows 78 g of carbs logged at 6:30 pm, a rapid-acting insulin dose at 6:25 pm, no exercise, and a note that says "restaurant." The 2h after dinner reading of 212 mg/dL appears in yellow because it is above the range set for that label.
Daily and weekly views, timestamps, and reports
Weekly BG Patterns displays seven days side by side, which makes it easier to spot readings that repeatedly run high or low at a particular time of day or around a particular meal. The grid uses the time each meal and workout was logged for, so turn on the food timestamp in Settings and correct it when you enter a meal late. Reports can cover 7 to 365 days, include any combination of trackers, and show your notes.
How does carb counting work in MyNetDiary?
MyNetDiary supports total carbs and net carbs. Choose one under Preferred Carbs Type and it applies to food entries, meal totals, the Dashboard, and the meal rows in BG Patterns. For diabetes management, the American Diabetes Association recommends counting total carbohydrate, because "net carbs" has no standard definition and some fiber and sugar alcohols still affect blood glucose.
Carb counts and logging speed
Set carbs as your primary or secondary nutrient and the count appears on each food entry without opening the Nutrition Facts panel. You can log by barcode, search, or voice in the free app, and Meal Scan (Premium) logs a plate from a photo. In our January 2026 test, the same 127 food entries took 711 actions in MyNetDiary versus 1,035 in MyFitnessPal, 31% fewer. When a packaged or restaurant food is missing, PhotoFood adds it from your photos, usually within hours.
Nutrition data
MyNetDiary provides highly accurate nutrition tracking on a staff-verified database of 2M+ foods built on USDA and NCC research-grade sources, with 2,500 to 3,500 foods reviewed and updated daily. The database supports up to 108 nutrient fields per food. How many are filled for a given food is its nutrient completeness. USDA and NCC records fill the most, and branded foods carry what the label declares. For diabetes, that means fiber, total and added sugars, sugar alcohols, sodium, saturated fat, and potassium next to carbs, plus detailed tracking of vitamins, minerals, and micronutrients.
How do BG check reminders work?
There are two kinds. From the Blood Glucose screen, you can set a one-off reminder for a specific time or interval, such as "in 15 minutes" or "in 1 hour." For post-meal checks, turn on After Meal Reminder Prompts and choose 1 hour or 2 hours. From then on, each meal you log automatically gets a BG check reminder for 1 or 2 hours after it.
After Meal Reminder Prompts
Each reminder is based on the meal's timestamp, so one setting covers breakfast, lunch, and dinner. You can switch between 1 and 2 hours, or turn the prompts off, at any time.
BG reminders, After Meal Reminder Prompts, and Report Email are currently iPhone features. Apple Watch shows the next check reminder and your BG averages.
Can I see blood glucose trends over time?
Yes. Health Charts plot blood glucose against your target band and limit lines, along with insulin, nutrients, and activities, for any period, with trend lines. BG Analysis on the web plots readings by time of day and reports the share in range, low, and high, with a median line.
A1C can be charted next to your daily readings, so you can compare the two-to-three-month lab average with the glucose patterns from the same period.
Can I track insulin and diabetes medications?
Yes. Turn on Show Insulin and choose from a catalog of 19 insulins grouped by type, including Lantus, Humalog, and Novolog, or add your own with Track New Insulin. Log the dose and time, add a label or a note, and the dose appears in BG Patterns and on the insulin chart. The Medications tracker records other medications, from metformin to GLP-1s.
The app records insulin doses; it does not calculate or recommend them. Dosing follows the plan from your diabetes care team.
If you use a GLP-1, GLP-1 Companion builds on the same medication tracker with injection-site logging, side-effect tracking next to meals, a protein-first plan, and two dedicated menus.
Other trackers for diabetes care
The same tracker system covers hemoglobin A1C, ketones (urine, blood, or breath), cholesterol (LDL and HDL), blood pressure, heart rate, weight, body measurements, and custom trackers for anything else. A1C, blood pressure, and cholesterol are three core measures in diabetes care, and they live in the same log as your food.
Share your log with your care team
On the web, you can print BG Patterns and any chart or save them as PDF or Excel. On iPhone, Report Email sends a 7-day summary. With Professional Connect, your dietitian, diabetes educator, or coach can view your food diary, blood glucose, and trackers as you log them, at no cost to the professional. MyNetDiary is used by dietitians and health professionals through Professional Connect.

Frequently Asked Questions
Is MyNetDiary a diabetes tracker app?
Yes. MyNetDiary includes a full diabetes module: blood glucose logging in mg/dL or mmol/L with labels and target ranges, insulin and medication tracking, A1C and ketone trackers, BG check reminders, and the BG Patterns view that lines up readings with meal carbs, insulin, medications, and exercise. It supports type 1, type 2, prediabetes, and gestational diabetes.
Is MyNetDiary free to use as a diabetes tracker app?
Food and carb logging, the barcode scanner, voice logging, water, exercise, steps, and weight tracking are free with no ads. The BG & Diabetes Tracking module, with BG Patterns, Health Charts, BG Analysis, insulin tracking, and BG reminders, is included in MyNetDiary Premium at $8.99 a month or $59.99 a year (current US pricing, verified September 2026).
Can I use MyNetDiary for prediabetes?
Yes. Choose Pre-Diabetes as your diabetes type to track fasting blood glucose, A1C, weight, carbs, fiber, and activity. The CDC's National Diabetes Prevention Program focuses on modest weight loss, healthier eating, and at least 150 minutes of physical activity per week, and food tracking helps you monitor those goals.
Does MyNetDiary connect to a CGM such as Dexcom or FreeStyle Libre?
Not directly. MyNetDiary receives blood glucose readings through Apple Health on iPhone and Health Connect on Android when your meter or CGM manufacturer's app shares them there. It also writes the readings you enter back to those platforms. There is no direct connection to sensors or meters, so check your device maker's current Apple Health or Health Connect support.
Does MyNetDiary calculate Time in Range?
No. BG Analysis reports the share of your logged readings that were in range, low, and high. Time in Range as reported by a CGM is based on continuous sensor data, and MyNetDiary does not compute it, including from readings imported through Apple Health or Health Connect.
Should I count total carbs or net carbs?
MyNetDiary supports both; pick one under Preferred Carbs Type. For diabetes management, the American Diabetes Association recommends counting total carbohydrate, because "net carbs" has no standard definition and some fiber and sugar alcohols are partly absorbed and can still raise blood glucose. Net carbs can be useful for people following a low-carb plan. Ask your diabetes educator which method fits your medication plan.
Can I track insulin and diabetes medications?
Yes. Log insulin from a catalog of 19 insulins grouped by type, or add your own, with dose, time, labels, and notes. The Medications tracker records any other medication, including metformin and GLP-1s, with reminders in Premium. Doses appear in BG Patterns and on the insulin chart.
Does MyNetDiary calculate insulin doses?
No. MyNetDiary records insulin doses but does not calculate or recommend how much insulin to take. Insulin dosing should follow the plan provided by your diabetes care team.
Can I share my blood sugar log with my doctor or dietitian?
Yes. Print, save as PDF, or export to Excel from the web, or send the 7-day Report Email from iPhone. With Professional Connect, your dietitian, diabetes educator, or coach can view your food diary and blood glucose readings directly, at no cost to the professional.
