How can we help?
Scan any label and know its glycemic index. Below are answers to the most common questions. If you need anything else, we’re an email away.
Frequently asked questions
What is the glycemic index?
The glycemic index (GI) ranks carbohydrate foods from 0–100 by how quickly they raise blood sugar. Low-GI foods (55 or under) cause a slower, gentler rise; high-GI foods (70+) spike it faster. FoodCheck GI shows this number instantly for whatever you scan.
How does FoodCheck GI work?
Point your phone at a nutrition label or a meal. FoodCheck reads it, identifies the food and portion, and returns the glycemic index, glycemic load, hidden sugars, and full nutrition — usually in a few seconds.
Is it accurate?
FoodCheck combines published glycemic-index research with AI analysis of the label or food in front of you. Nutrition labels are the most precise input; meals and whole foods are estimated. Published GI values naturally vary between studies, so we treat the result as well-sourced guidance, not a lab measurement.
Do I need to wear a glucose monitor?
No. FoodCheck GI works entirely from your phone’s camera — there’s no sensor to buy and nothing to wear. It’s a fast, affordable way to understand foods before you eat them.
Is FoodCheck GI free?
Yes, you can start scanning for free. FoodCheck Pro unlocks unlimited scans and the full feature set. FoodCheck GI is available on Google Play and the App Store.
Can it help with diabetes or weight loss?
Many people use FoodCheck to choose lower-GI foods for steadier blood sugar or appetite control. It’s an educational tool, not medical advice — always follow the guidance of your doctor or dietitian.
How do I scan a label?
Open the Scan tab, point your camera at a nutrition label, and tap the shutter button. You can also import an existing photo from your library.
Why does the app need camera and photo access?
Camera access is needed to capture labels, and photo access lets you import existing photos. You can revoke either permission at any time in your device settings.
What’s the difference between Gemini and Claude?
Gemini is faster and great for everyday scans of clear labels. Claude takes a moment longer but produces deeper analysis and more accurate hidden-sugar detection.
What’s the difference between Free and Pro?
Free includes a daily scan quota. Pro unlocks unlimited scans, full history, shopping lists, and access to Claude.
Can I save my scans?
Yes. Tap the star to save a scan to Favorites, or open History to see everything you’ve scanned.
What languages does FoodCheck support?
English, Spanish, Portuguese, French, German, Italian, and Russian.
