GlucoSpike AI 100% free · No subscription needed
Scan any barcode. Know before you buy.
"Sugar-free" on the label doesn't mean spike-free in your body. Point your camera at any packaged product and get an instant GS Score — how it will hit your blood sugar, and what to grab instead. Free for everyone, because knowing what's in your food shouldn't cost anything.
Scanner is free forever • No credit card required
Open Food Facts. Your whole supermarket.
Product data comes from Open Food Facts, a public nonprofit food database maintained by contributors around the world. Because it is open, anyone can check what is in it — and coverage is strongest where contributors are most active. A product that is not in the database returns no verdict rather than a guessed one.
What you get per scan
A verdict, not just a nutrition table.
An instant GS Score (0–10)
The same glucose impact rating you get for home-cooked meals, now for anything with a barcode — with a Minor, Moderate, or Major Impact verdict in plain language.
Why — in one sentence
"Despite being sugar-free, this product is extremely high in refined carbohydrates and lacks the fiber or protein needed to prevent a significant glucose spike." No label math required.
What to note, and what to grab instead
Ranked warnings — carbohydrate density, missing protein and fiber, fast-digesting starches — plus a smarter alternative to look for in the same aisle.
Recent scans stay on hand
Every product you check is saved with its GS Score — so the second time you're in the aisle, the answer is already in your pocket. Save any scan as a meal to count it toward your day.
Scanner questions
Is the scanner really free?
Yes — completely free, no subscription, no trial clock. We believe everyone deserves to know how packaged food will hit their blood sugar. Meal snapping, the AI coach, and pattern tracking are part of the full app with a 7-day free trial.
Does it work in my country?
Product data comes from Open Food Facts, a public nonprofit food database covering 4M+ products across 150+ countries, and growing. Because contributors maintain it, coverage is strongest where they are most active — a product that is missing returns no verdict rather than a guessed one.
Do I need a CGM or glucose monitor?
No. GlucoSpike uses food science and AI to predict how a product will affect your blood sugar — no wearable or device needed.
What if a product isn't in the database?
Snap a photo of the nutrition label instead — GlucoSpike reads it and scores the product the same way. We continuously expand the food database.
