FAQ
Good to know
How does the AI food scanner count calories from a photo?
It uses an AI vision model to identify the foods on your plate, estimate their portion sizes, and look up their nutrition — returning calories and macros in seconds. Every value is editable for an exact log.
How accurate is AI food scanning?
AI food recognition is typically 85–95% accurate on single foods and 65–80% on mixed meals — plenty to track trends. You can separate ingredients, add a size reference and edit portions to push accuracy higher.
Do I need to weigh my food?
No. LensNutra estimates portions from the photo, so you can log without a scale. For more precision, adjust the serving size or scan a barcode instead.
Is there an app that counts calories from a photo?
Yes — LensNutra is a calorie counter that works from a photo. Take a picture of your meal and it identifies the food, estimates the portions, and logs the calories and macros automatically, with no manual entry or database searching.
Can I get my macros — protein, carbs and fat — from a photo too?
Yes. Every scan returns calories plus protein, carbs, fat and fiber for the whole meal and each ingredient, so you can track your macros from a single photo.
Do I have to type anything or search a food database?
No. The photo does the work — no typing and no searching a database. When you want exact packaged values, you can still scan a barcode or nutrition label.
Does it work for restaurant meals, takeout and home cooking?
Yes. Snap a home-cooked plate, a restaurant dish or takeout and the AI estimates it. For packaged products, the barcode and label scanners give precise numbers.
