How Nourli Works

Nourli is a nutrition tracker that uses AI to turn a photo of your food into a calorie and macro breakdown. It runs on iOS, Android, and any web browser.

Beyond food tracking, it includes a personal AI nutrition coach that knows your goals and your food log, an intermittent fasting timer with metabolic stage tracking, water and weight logging, and detailed analytics. Everything syncs across your devices.

You photograph your meal. The AI examines the image and identifies individual food items - a chicken breast, a cup of rice, a side of broccoli. For each item, it estimates the portion size and calculates calories, protein, carbs, and fat.

The whole process takes a few seconds. It handles everything from a simple banana to a complex restaurant plate with six different components. If your dish contains hidden ingredients like cooking oil or butter that the camera cannot see, you can add a text description to improve the estimate.

Each item comes back as a separate entry, so you can edit or remove any individual food without affecting the rest of the meal.

For common, clearly visible foods - a grilled chicken breast, a bowl of oatmeal, an apple - estimates are typically within 10-20% of actual values. Accuracy is highest when food items are distinct, well-lit, and photographed from above.

Accuracy drops when key details are hidden. Sauces, oils used in cooking, cheese melted inside a wrap, dressings on the side that get poured on - the AI can only work with what it can see. Describing these extras in the text field makes a real difference.

You should treat the numbers as a solid starting point, not lab measurements. Every value is editable after logging. Over time, slight overestimates on one meal tend to offset slight underestimates on another. The trend matters more than any single entry.

For anyone managing a medical dietary condition, these estimates are not a replacement for working with a registered dietitian. See our health disclaimer for details.

The whole thing takes under 10 seconds for most meals. If you prefer not to use photos, there is also a manual entry option where you type in the food name and values yourself.

The coach is a chat interface that has access to your food log, your nutrition goals, your recent weight entries, and your frequently eaten foods. You can ask it things like:

• “What should I eat for dinner? I have 600 calories left.”
• “Was my protein intake good this week?”
• “Give me a high-protein snack idea under 200 calories.”

It responds based on your actual data, not generic advice. If you have 40 grams of protein left for the day and a fasting window opening in two hours, it accounts for both.

The coach is not a doctor or dietitian. It provides general nutrition guidance and should not replace professional medical advice.

Nourli includes a full intermittent fasting timer. Six built-in plans are available: 14:10, 16:8, 18:6, 20:4, OMAD, and a custom option from 1 to 72 hours.

While a fast is active, the timer tracks your progress through 10 metabolic stages - from the fed state through glycogen depletion, fat burning, deep ketosis, and autophagy activation. Each stage shows what is happening in your body and which hormones are involved.

Safety features activate automatically as fasts get longer. A medical disclaimer appears before starting fasts over 18 hours. Emergency symptom alerts show at 24 hours. There is a hard cap at 72 hours. The AI coach is also aware of active fasts and will not suggest meals during your fasting window.

Water. Quick-add presets (glass, bottle, large, liter) or custom amounts. Supports both milliliters and fluid ounces. Your daily intake shows on the Today screen with goal progress, and full history is available in the History tab.

Weight. Log entries over time in kilograms or pounds. Entries are grouped by month in your history, and your recent weight data feeds into the AI coach so it can give advice based on actual trends.

Burned calories. Enter your daily total from a fitness tracker or smartwatch. This gives you a full energy balance view alongside your food intake. Each entry replaces the previous total for that day.

Goals. Nourli calculates calorie and macro targets using the Mifflin-St Jeor equation, factoring in your age, height, weight, sex, and activity level. You can override any value with a custom target. Protein, carb, and fat ratios are fully adjustable for keto, vegan, high-protein, or any other approach.

Everything feeds into the Analytics tab, which shows weekly calorie patterns, macro distribution, nutrient trends, and long-term progress.

Food photos are processed in memory and deleted immediately after analysis. No images are stored on any server, database, or third-party system. Only the resulting text data - food names, calorie and macro numbers - is saved to your account.

The service is GDPR and CCPA compliant. You can export all your data or delete your entire account at any time from Settings. Nourli is based in the European Union and subject to EU data protection law. Read the full privacy policy.

Nourli uses the latest available AI models for both food recognition and the nutrition coach. The app is not locked to a single model or provider. When something better becomes available, it gets integrated - typically within weeks of release.

This means the accuracy and quality of responses improve over time without you needing to update anything. The models used for food analysis are separate from the models used for the coach, and each is chosen for what it does best.

Every new account starts with a 7-day free trial. All features are unlocked from day one - there is no limited free tier.
