Frequently asked
Is Carb Lens free?
Yes. You get 2 AI meal scans every day for free, plus unlimited access to guided workouts, the dashboard, and your daily health score. Pro unlocks unlimited scans, glucose-response forecasts, smart swap suggestions and an ad-free experience.
How accurate is the AI nutrition scanner?
Carb Lens uses a multimodal vision model to detect each item on your plate, estimate portions, and return carbs, sugar, protein, fat and calories to the nearest tenth — with a confidence score you can re-analyze in one tap.
Do I need to log workouts manually?
You can. Pick a guided 5–15 minute routine from the workouts library, or log any workout you do outside the app — both feed into your weekly trends and your health score.
Does Carb Lens work on iPhone and the web?
Both. Your account, scans, streak and subscription sync across the iOS app and carblens.org — sign in with the same email.
Is Carb Lens a substitute for medical advice?
Carb Lens is a tracking and education tool. It's designed to be accurate enough to inform everyday decisions, but it's not a substitute for advice from a licensed healthcare professional.
