One nutrition toolkit
More than a calorie counter.
01

03
Recipe analyzer

04
Personalized suggestions
Set your goals, activity level and dietary preferences for more relevant guidance.
A thoughtful note
Useful guidance, not medical advice.
Nutrition values and allergen detection are AI-generated estimates and can be imperfect. Always check packaging, recipes and professional guidance when an allergy, health condition or medical decision is involved.
Questions
Before your first scan.
Do I need to log every ingredient?
No. Take a photo or choose one from your library and NutriLens analyzes the visible meal for you.
Can NutriLens scan restaurant and homemade food?
Yes. It is designed for plated meals, homemade dishes, restaurant food, snacks and leftovers — not only packaged products.
Are the calorie and macro results exact?
They are AI-powered estimates. Portion size, hidden ingredients and preparation methods can affect accuracy.
One photo. A clearer food choice.
Make nutrition easier to understand with NutriLens, or estimate your daily targets first with the free calculator.
Make the first step practical.
Start with a meal you know
Photograph a familiar lunch, review the identified foods and compare the estimate with any recipe or label information you have. NutriLens helps you explore the meal’s nutrition; the portions, sauces and ingredients you know about give the result useful context.
Build a record you can revisit
Use the food-photo and homemade-meal guides to keep portion assumptions consistent. Saved scans and deeper analysis may require an in-app purchase. A photo estimate cannot verify allergy safety or replace individualized nutrition advice.
Food tracking and nutrition guides
NutriLens analyzes meal photos and provides estimated calories and macronutrients. Check the identified food and portion before using a result. Hidden ingredients and cooking methods can change the estimate.
