Common questions.

How accurate is the carb count?: AI estimates are cross-checked against the USDA FoodData Central database on every scan. You can edit any value if you know better — you stay in control. For medical decisions like insulin dosing, we recommend treating estimates as a starting point and adjusting based on your CGM and your care team’s guidance.
Does CarbZen replace my CGM or glucose monitor?: No. CarbZen is a carb-counting tool, not a medical device. It helps you estimate what you’re about to eat so you can make informed decisions. Pair it with your CGM for the full picture.
Do I need an account?: Never. CarbZen has no sign-up, no email capture, no profile. Open the app and scan. All history stays on your device.
What happens with my meal photos?: Photos are analyzed through our proxy, stripped of metadata, and discarded immediately after analysis. Only the carb estimate and a local thumbnail are saved to your device. Full details in our privacy policy.
Does it work for mixed dishes, restaurants, and home cooking?: Yes. CarbZen identifies multiple items on a plate and gives you a per-item breakdown — that’s the whole point. Barcode scanners fail at restaurants. Cameras don’t.
Is it really free?: Yes. 3 full scans every day, forever. No trial expiring, no card required. Upgrade to Pro ($4.99/mo or $29.99/yr) only if you want unlimited scans and the full macro breakdown.
