Better meal scans

AI food recognition can identify common foods quickly, but no photo-only calorie scanner is perfectly accurate. The most useful products make uncertainty clear and let you correct the result.

Portion size is difficult to judge without a known scale. Hidden ingredients, oils, sauces and recipes also change nutrition. Restaurant dishes can vary substantially even when they share the same name.
How to take a better food photo
Use bright, even light; include the whole plate; avoid covering one food with another; and photograph from an angle that shows depth. If possible, separate sauces or describe ingredients that are not visible.
Use the estimate as a starting point
A consistent estimate can still make a food diary easier. Review the detected meal, adjust the serving when needed and look at trends across days and weeks instead of treating one scan as laboratory measurement.
