NutriLens AI — Calorie Tracker

NutriLens AI is your AI-powered calorie counter and food tracker. Skip manual food logging — snap a photo of any meal and get instant calories, macros, and nutrition facts. Track intermittent fasting, log workouts, scan barcodes, get AI meal plans, and stay motivated with friends and challenges — all built around your goals.
📸 AI PHOTO FOOD SCANNER
The most powerful feature in NutriLens AI. Point your camera at any meal — home cooked, fast food, restaurant, or snack — and this AI calorie counter instantly detects calories, protein, carbs, fat, fiber, and more. No manual food logging needed.
⚡ QUICK LOGGING
Log repeat meals and recent foods in seconds. Your regulars appear right where you need them, so re-logging a meal you've already tracked takes one tap.
📈 ADAPTIVE WEEKLY CALORIE TARGETS
NutriLens AI learns from your real results. Once you've logged enough nutrition and weight data, it compares your actual trend against your goal — lose, maintain, or gain — and suggests a small calorie adjustment (never more than ±150 kcal/day) with matching macro changes. Nothing changes until you tap Apply, and your adaptive target carries forward across weigh-ins and app restarts.
⏱ INTERMITTENT FASTING TRACKER
Track any fasting plan from 12:12 to 23:1 with an animated progress ring. See exactly which fasting stage your body is in — blood sugar regulation, fat burning, ketone production. Set your fasting window and build a habit that lasts.
✨ AI NUTRITION COACH
Chat with your personal AI nutrition coach anytime. Ask about your macros, get meal ideas, understand your calorie tracker data, or learn about nutrients — all personalized to your goals.
🗓 AI MEAL PLANNER
Get a personalized 14-day meal plan generated by AI in seconds. Every meal plan is tailored to your calorie goal, diet type, and food preferences. Regenerate your meal plan anytime for something new.
