Latest in iDC v1
More ways to find foods and plan your meals
The latest development build adds food scanning and more tools for everyday use. These features are part of the app being tested; public downloads are still coming soon.
Scan a product barcode
Scan a packaged food with your camera, or enter its barcode, to look up a matching product in Open Food Facts. Review its nutrition before adding it to your meal.
Search Open Food Facts
Search packaged foods by name alongside your saved iDC foods. Review carbohydrate, sugar, fibre and protein values per 100 g, with a link to the original product record.
Offline photo suggestions on iPhone
Take or choose a photo to get possible common food names or text from a package label. Recognition runs on your iPhone and the photo stays on your device. Suggestions still need checking.
Save your usual meals
Save regular meals to Favourites and load them again when planning breakfast, lunch or dinner. Adjust the food quantities for the meal you are having today.
Backup and restore
Export a backup of your profile, foods, settings and meal history, then restore it in iDC when needed. Keep your backup file somewhere safe.
More ways to share your history
Export meal history as CSV, or prepare a clinical summary, clinician report or detailed meal report to share with your care team when you choose.
From finding a food to reviewing your meal
- Find a food Scan a barcode, search by name, or use photo suggestions on a supported iPhone.
- Check the nutrition Confirm the food identity and all four nutrient values per 100 g against the label or a trusted source. Missing values stay blank.
- Choose your portion Enter a measured portion in grams. Confirmed foods are saved locally for reuse.
- Review the calculation After you tap Finish, the calculation panel appears above Scan food and scrolls into view for review.
A photo does not determine nutrition, allergens, portion size or an insulin dose. New online product lookups need an internet connection; saved foods remain available offline. Offline photo recognition is currently an iPhone feature, while Android supports barcode and name search.
Product data: Open Food Facts, a community database licensed under ODbL. Records may be incomplete and must be checked.
About Insulin Doses Calculator
Insulin Doses Calculator is a simple, intuitive insulin dose calculator designed to support people living with diabetes in making informed decisions around insulin dosing. Built for both Type 1 and insulin-dependent Type 2 diabetes, the app helps users better understand how food intake, blood glucose levels, and personal insulin settings work together.
The app allows users to log meals, view nutritional information, and receive insulin dose recommendations based on their individual insulin-to-carbohydrate ratios and correction factors. By combining structured data with intelligent calculations, Insulin Doses Calculator aims to reduce guesswork and bring greater confidence to everyday diabetes management.
With a clean, user-friendly interface, the app makes it easy to:
- Record meals and nutritional values
- Track blood glucose history
- View meal history and insights
- View trends over time with charts and graphs, 7, 14, 30 & 90 day views
- Generate dose guidance tailored to the user
- Generate enabled Clinician Summary or item by item report with the Clinician.
Insulin Doses Calculator is designed as a supportive tool, not a replacement for medical advice. All recommendations are intended to complement guidance provided by healthcare professionals, empowering users to stay informed, organised, and in control of their routine.
The app is currently in development and will be available for download in the future.

HbA1c conversion chart
An iDC bar chart showing selected HbA1c conversions between % and mmol/mol, with a key explaining the six colour bands.
The two-page PDF includes clinical context and linked references. Save a copy or print it to discuss with your diabetes care team.
The ranges have been checked against diabetes.co.uk and Diabetes UK; the six colours help you read the chart. Agree your personal HbA1c target with your diabetes care team.
Step-by-step tutorials
Get to know each part of GlucoPlan
Start with tutorial 1 and follow the numbered order. Each walkthrough explains the buttons, steps and important checks using the current app screens.
Profile settings
Read this tutorial’s transcript
Open Profile
Start with Profile in the bottom menu. This is where GlucoPlan keeps the settings used for meal calculations and classification. Work through the whole page before planning meals. The values in this demonstration are examples; use the settings agreed with your own clinical team.
Check ratio type and units
At the top, check Default Ratio Type and Unit of Measure. The ratio switch selects Sugar Ratio or Carbs Ratio. The unit switch selects millimoles per litre or milligrams per decilitre. Match the displayed glucose unit to your meter before entering readings elsewhere in the app.
Review both ratios
Review both ratio fields, even when only one is currently selected. Each field is labelled one to x, and accepts a value with one decimal place. Do not copy the demonstration values. A zero ratio cannot be used as a divisor when finishing a meal.
Understand auto-selection
Auto-select ratio per meal allows the app to choose a ratio type from the meal classification. Below it are the carb-heavy and sugar-heavy thresholds. Net carbs means total carbohydrates minus fibre. Sugar share is entered from zero to one, so point two means twenty percent.
Set follow-up preferences
Post-meal reading reminders store a due timestamp to support follow-up in meal history. The delay field becomes available when the option is enabled, and its supported range is thirty to three hundred and sixty minutes. Treat this as a recording aid; do not assume a phone notification has been scheduled.
Save and confirm
Finally, tap Save Settings and check the saved status and Last updated information. Return to Meal Plan and confirm that the displayed ratio type and glucose unit match. Profile also contains Backup and restore, which has its own walkthrough. Revisit these settings whenever your agreed plan changes.

Frequently Asked Questions (FAQ)
Insulin Doses Calculator (iDC) is a support tool designed to help people with diabetes estimate insulin doses. It does not replace professional medical advice.
How does food scanning work?
Scan or type a product barcode, or search by name, to find foods in Open Food Facts. You must check the food identity, carbohydrate, sugar, fibre and protein values per 100 g before confirming it. Then choose your portion in grams. New online lookups need an internet connection.
Can iDC identify a meal from a photo?
The updated iPhone app can suggest common food names or read package-label text using offline recognition. Photos stay on the device. It is not a comprehensive mixed-meal recogniser: a suggestion may be incorrect or no match may be found. A photo does not supply nutrition values, allergens, portion sizes or doses. Android currently supports barcode and name search.
Can I reuse foods and meals or make a backup?
Confirmed foods are saved locally and can be reused offline. Regular meals can be saved to Favourites and loaded again. The database screen also lets you export and restore a backup of your profile, foods, settings and meal history. Store backup files safely because they contain your personal information.
