From photo to logged meal
1 · Snap
Point the camera at your plate. On LiDAR iPhones, depth measures the scene while you shoot.
2 · Review each food
Every detected item is listed with grams, calories and a confidence level — no black-box total.
3 · Confirm in one tap
High-confidence items pass by default; only uncertain ones ask you a quick question.
4 · Know what's next
After each log: what's left today and one concrete suggestion — never a lecture.
How accuracy works
Nutrition from a photo is an estimate. We make it a good one — and we show our work.
Identify
A vision model names each food and its likely ingredients.
Portion
Depth (LiDAR) measures your plate, so portions come from geometry — not a guess from a flat photo.
Nutrition
Per-item calories and macros, cross-referenced against USDA FoodData Central.
You correct
Everything is editable in one tap. Low-confidence items are flagged, never buried.
Where we're honest about limits
- Hidden oils, butter and dressings can be underestimated
- Mixed or stewed dishes are harder than separate items
- Foods hidden under other foods can be missed
- Shared plates need you to say how much was yours
When we're less sure, the item is marked for review instead of pretending precision.

Frequently asked questions
- How accurate is it?
- Portion size is the hardest part of photo nutrition. Metriful measures it with depth where available and keeps every number editable. Treat results as good estimates, not lab measurements.
- Do I need a LiDAR iPhone?
- No. Depth improves portion accuracy on iPhone Pro models; on other devices Metriful still itemizes your meal from the photo and you can adjust portions in one tap.
- What happens to my meal photos?
- They're uploaded securely to create your log and stay attached to your account until you delete the meal or the account. See the Data Deletion page for the full process.
- Is the glycemic estimate medical advice?
- No. It's a general estimate derived from carbohydrate content — not a personal blood-glucose prediction. Metriful provides general wellness information, not medical advice.
