Our mission
Make every meal an informed choice.
Carb Lens is built by a team of engineers, dietitians, and nutrition advisors who believe everyone deserves tools as careful and modern as their health goals.
Our core values
Health-first
Every feature is designed around the question: does this make a healthier decision easier?
Clinically informed
Our nutrition models are reviewed by registered dietitians and validated against USDA datasets.
Privacy-respecting
Photos are processed on-device when possible. We never sell health data, ever.
Accessible by default
Voice, large type, screen reader, and colorblind-safe indicators are not afterthoughts.
Free All-in-One Alternative
The free alternative to MyFitnessPal, Cal AI, SNAQ — and the only one with workouts built in.
