How accurate is photo scanning?

For most everyday meals, photo scanning lands within 10 to 15% of a weighed estimate. Close enough to guide your day, and far better than not logging at all.

What the scanner is good at

Plated meals with visible components scan well: a bowl, a plate, a sandwich. The scanner identifies each ingredient, estimates portions from the photo, and shows calories with protein, carbs and fat.

Where to double-check

Hidden ingredients are the usual gap: oil in a stir-fry, butter in a sauce, sugar in a dressing. Soups and stews also hide their contents. After a scan, adjust any portion or use Fix with AI to correct the result in plain words. The estimate updates right away.

When to use something else

Packaged foods have exact labels, so scan the barcode instead. For a meal you cannot photograph, describe it in plain words and MealSnap estimates from the description.
