Everything the app can do today – to look up before you download it.
Estimating
Carbs in seconds – even where there's no label to read.
Snap your plate. The AI estimates the carbs in grams and converts them to BE or KE – at the kebab shop, in a restaurant or for grandma's cake. It also tells you where the numbers come from.
The AI estimates, it doesn't measure. Check every value before you save it – the 3-hour check shows you afterwards whether it was right.
Every photo is estimated twice, and a third time if the answers differ. If the results are far apart, GlucoMatch tells you – instead of faking a certainty that isn't there. If you prefer speed, you can switch it off.
The AI saw cow's milk, but it was oat milk? Add a quick note and it estimates the same photo again. Up to three times per photo.
Save what's always the same for you – e.g. “coffee always with oat milk” or “bread usually gluten-free”. The AI uses it for every photo where it fits and shows you what it took into account. One tap turns a correction into a preference.
Scan the barcode, pick the amount – the values come straight from the label, via the free Open Food Facts database. No AI involved. GlucoMatch supports Open Food Facts with a donation every year.
From the same photo, the AI also estimates calories, protein and fat – right in the result and in the 3-hour check.
For every photo, the AI estimates how quickly the carbs are absorbed – fast, medium, slow or delayed, with a rough duration – plus the glycaemic load.
For information only: the app never derives an injection time or a dose from it.
Learning
So you estimate better next time – with or without the app.
After 3 hours GlucoMatch reminds you: was the estimate right? If you were off, you adjust the value. When a check is due, a number appears on the app icon.
You choose the duration yourself.
Every confirmed meal goes into your memory. Eat it again and you start from your own value instead of a new estimate – and see whether it worked last time. Your most frequent meals are ready on “Today”.
How often was your estimate right over the last four weeks? Your hit rate shows it, with a trend and a hit streak.
Badges, levels and streaks reward sticking with it – for example ten estimates that were right. You can share every badge as an image.
Which meals do you usually get wrong – and in which direction? For example: “Pizza: usually ~1.5 KE too low”. Based on all your 3-hour checks.
It's only about estimating carbs, never about insulin.
Diary & doctor
Everything in one place – as clear as on paper.
Meals, bolus, basal, activity and notes in one timeline, from morning to night. Swipe between days or jump straight to one in the calendar. Forgot something? Add it up to 7 days later.
Log a bolus from the “+” – with a sensor, your current glucose is already filled in. Your basal is ready at your usual time and confirmed with one tap. “Today” shows roughly until when a bolus is active.
Logging only: GlucoMatch does not calculate insulin doses.
Note your insulins and tablets with your own comments – handy at the doctor's or when travelling. Just a note for you: the app calculates nothing with it.
A PDF with your glucose profile, time in range, GMI and every day with its curve, meals and insulin. Created on your phone, sent by email or messenger – wherever you like.
7, 14 or 30 days: average glucose, time in range, GMI and glucose profile – plus carbs, bolus and basal per day and how often your estimate was right.
Glucose values need Nightscout or Dexcom.
Sensor
Glucose values right in the app – always from one source.
Connect your Nightscout: your current value with trend arrow at the top of the app, your curve on “Today” – and your glucose is already filled in when you log a bolus or a 3-hour check.
Sign in with your Dexcom account – for G6 and G7, via Dexcom Share, like the Follow app. The app only reads. Your password stays encrypted on your phone, and for the report and statistics it keeps your values for up to 90 days on the device.
“Share” must be switched on in the Dexcom app.
Your way of counting
The app adapts to how you were taught, not the other way round.
Grams, BE or KE – with 10 or 12 g per unit. Glucose in mg/dL or mmol/L. The app speaks English or German, and the AI answers in your language.
Only want to see calories, without reminders? Switch the timer off and meals are saved without a 3-hour check. Or set your own duration.
Your data
No account, no server – and quiet if you want it.
No account, no server: meals, photos, insulin and glucose values stay on your phone. Only the photo with your notes goes to the AI for analysis, and only the number to Open Food Facts for a barcode. Delete the app and everything is gone.
All core features are free; in return, the free version shows unobtrusive ads. GlucoMatch Plus removes them and gives you every feature with this badge. €0.99 a month or €9.99 a year, through Google Play or the App Store.
What we're working on right now is in the roadmap on the home page.

GlucoMatch is a diary that helps you estimate. The app does not calculate or recommend insulin doses and does not replace diabetes education or medical advice.
