iPhone
CarbLens estimates carbohydrates and macros from a single meal photo — no food lookup, no barcode scan, no guessing from a database entry that might be wrong by 40g.
Point your camera at any meal. CarbLens uses on-device AI to estimate carbs, protein, fat, and calories with a confidence band in under four seconds. Every analysis stays on your device — no photo is ever uploaded.
Log to Apple Health in one tap. CarbLens writes your carb count directly to HealthKit, then pulls in your blood glucose readings so you can see exactly how each meal moved your numbers.
Built for people who count carbs for insulin:
• Instant photo-to-carb estimate — restaurants, home meals, anything
• Confidence band shows estimation uncertainty before you dose
• Glucose curve overlaid on every logged meal
• Live Activity tracks your meal absorption window on the Lock Screen
• Weekly patterns surface where your estimates run high or low
• Siri: "What did I last eat?" / "Log my meal with CarbLens"
• 100% on-device — your food photos and glucose data never leave your phone
CarbLens is a dietary estimation tool. It is not a medical device and does not provide insulin dosing recommendations. Always apply your own clinical judgment and follow guidance from your healthcare provider.
Available for iPhone with iOS 26 or later.
