How does NutriSnap AI calculate calories from a food photo?

NutriSnap uses High-Context Neural Vision Protocol to detect visual reference markers such as plate diameter, bowl depth, and utensil sizing to estimate 3D physical portion volume and gram weights, then computes calories, protein, carbs, fats, and fiber instantly.

Is AI calorie tracking accurate compared to using a kitchen food scale?

NutriSnap accounts for cooking methods (e.g. grilled vs. deep fried), oil absorption, and hidden sauces, achieving up to 98% portion accuracy with the ability for users to tap and adjust individual ingredient gram weights in real-time.

Does NutriSnap support barcode scanning for packaged foods?

Yes! NutriSnap features an instant 1-tap camera barcode scanner connected to an international database of over 3 million foods (Open Food Facts + AI Fallback) to retrieve exact nutrition facts from any product package.

Can I use NutriSnap on iPhone and Android without downloading an app store file?

Yes, NutriSnap is built as a Progressive Web App (PWA). You can tap "Add to Home Screen" on iOS Safari or Android Chrome for an instantaneous native app experience with offline capability and instant load times.

How does the 3-day free trial work?

Every new user receives 3 full days of unlimited AI meal scans, barcode lookups, and dietitian feedback 100% free with zero upfront charges. You can choose to upgrade to Pro anytime or continue exploring.

Can I re-log my favorite meals with 1 click?

Yes! NutriSnap includes a dedicated Favorite Meals hub with 1-Tap Quick Re-Log. Any meal you star is saved as an independent entity that you can log into today's diary with a single tap, even if you clean your past history.
