Yes, Gutman AI is free to download on the App Store.

Estimates are calibrated against USDA FoodData Central and include per-item confidence scores you can adjust. On LiDAR-equipped iPhones, depth data improves portion sizing.

Your targets are deterministic: they are computed on your device from established U.S. nutrition guidelines rather than generated by AI, so they are consistent and reproducible. Calories use the Mifflin-St Jeor equation with an activity multiplier and a goal adjustment (lose, maintain, or gain) and a safety floor. Protein is set by your body weight per the Dietary Reference Intakes (about 1.6 g/kg maintaining, up to 1.8 g/kg when losing or gaining, capped at 2.0 g/kg). Fat follows the Acceptable Macronutrient Distribution Range (around 30% of calories, adjusted for gut conditions or diabetes) and carbohydrate fills the rest. Set your Activity level and Goal in Settings and targets recompute instantly. Kids use U.S. pediatric standards (the National Academies Estimated Energy Requirement, the pediatric protein RDA, and age-appropriate macro ranges).

Metabolic age is an educational estimate anchored to your BMI: a healthy BMI reads close to your actual age, while a higher BMI reads older. Gutman records one snapshot per day per profile so you can follow the trend in the Progress tab. It is computed locally, stored on your device (not uploaded to the cloud), available for adult profiles, and is an estimate, not a medical measurement.

Gutman AI offers Continue with Google and Continue with Apple. Email and password account creation is no longer available because verification-email delivery was unreliable. You can add an optional Face ID / Touch ID lock inside the app.

Yes — it recognizes regional cuisines, including Indian dishes, and the AI coach tailors suggestions to where you're from.

Yes. In Profile then Profiles you can create child profiles that you manage as the parent (with a consent step), switch between them, and share a child with another parent or guardian by email or Gutman ID (GID). Guidance for kids follows the U.S. Dietary Guidelines and the American Academy of Pediatrics, and it is de-identified: a child's name and birth date are never sent to the AI.

Yes. Each meal gets an estimated glucose-impact curve labeled Low, Moderate, or High, based on its carbs, fiber, protein, and fat. If you use a CGM connected to Apple Health, your real post-meal readings are overlaid on the estimate. It's educational information, not medical advice, and not for insulin dosing; for kids it stays soft and non-numeric and defers to a pediatrician.

iPhone on iOS 26.2 or later. Some features, like LiDAR portion sizing, require Pro models.

Grant permission when prompted, or in iOS Settings → Privacy & Security → Health → Gutman AI. Height, weight, and active energy sync to personalize your targets. The height and weight you enter in Edit Profile are the source of truth, and you can switch units live between kg/lb and cm/ft-in.
