All premium features are FREE for a limited time. Unlimited AI photo scans, 10 diet protocols, AI coaching, and weekly report cards. Download and enjoy.
Stop guessing what's in your food. Snap a photo and know in seconds.
Nibble turns any meal photo into a complete nutrition breakdown — calories, protein, carbs, fat, and 20+ micronutrients. Then tracks your compliance across 6 diet protocols with an AI coach that knows your meals, your goals, and your habits.
FOUR WAYS TO LOG EVERY MEAL
• AI Photo Analysis — snap a photo and AI identifies every item on your plate
• Barcode Scanner — scan packaged foods for instant nutrition data
• Nutrition Label Camera — photograph any nutrition label for automatic entry
• USDA Database — search 17,000+ verified foods
No manual searching. No guesswork. No typing "chicken breast 6 oz" ever again.
PICK YOUR PROTOCOL. WE HANDLE THE REST.
Choose from 6 diet protocols, each with AI-personalized daily targets:
• CICO — calorie deficit tracking with adaptive targets
• Keto — net carb tracking and ketosis-friendly scoring
• Intermittent Fasting — eating window monitoring with timing alerts
• Low-Carb — carb percentage targets and daily breakdowns
• Mediterranean — compliance scoring based on food classification
• Carnivore — food category tracking for strict protocols
AI calculates your targets based on your body, goals, and activity level. A monthly compliance calendar shows exactly how well you're sticking to your plan — green, yellow, or red for every day.
YOUR OWN AI DIET COACH
Chat with a coach that actually knows what you ate today. Ask for meal suggestions, get feedback on your week, troubleshoot a plateau, or plan tomorrow's food. It's like having a nutritionist on call — for a fraction of the cost.
WEEKLY & MONTHLY REPORT CARDS
Every week and month, AI grades your nutrition from A to F. See what you nailed, where you slipped, and exactly what to adjust. No vague advice — specific, actionable feedback based on your actual meals.
PROGRESS THAT KEEPS YOU GOING
• Macro trend charts across 1-week to 3-month ranges
• Weight tracking with smoothed trend lines and plateau detection
• Daily calorie deficit and surplus tracking
• Nutritional sufficiency indicators for vitamins and minerals
GAMIFICATION THAT WORKS
