Dish scan to calorie estimate

A calorie counter app that works from a photo

Take one photo of your meal and Frittu lists what's on the plate, with an amount for each item. Fix anything that's off and you get an estimate of the calories, protein, carbs, fat and fibre. One tap logs it to today's meals.

A photo can't weigh food, so every figure is an estimate. What helps most is checking the amounts before you log, and Frittu marks the ones it's least sure of.

How it works

  1. Photograph the plate

    Home-cooked, takeaway or from a restaurant. Frittu names the dish and lists each item with an amount and how it was cooked.

  2. Check the items and amounts

    Rename, add or remove items and change amounts. An amount Frittu isn't sure of is marked Check amount. A mixed dish like a curry or lasagne counts as one dish, sauce and cooking fat included.

  3. Get the estimate and log it

    See calories, protein, carbs, fat and fibre, item by item. Log it to breakfast, lunch, dinner, a snack or your own meal slot for today.

How accurate are photo calorie counters?

Less accurate than they look. In a 2026 test led by US National Institutes of Health researchers, four popular photo-based apps were given photos of more than 100 meals whose every ingredient had been weighed. On average the apps came in 250 to 345 calories low, mostly because they underestimated fat and portion size. The findings were presented at a nutrition conference and are preliminary.

The lesson is the same for any photo estimate: the amounts matter most. A tablespoon of oil, a bigger scoop of rice or a hidden layer of cheese can change the total by hundreds of calories.

What you can correct before it counts

Every estimate in Frittu is built from a list you can see. Change an amount, add the oil or butter it couldn't see, or remove something that isn't there, and the estimate follows.

Link an item to a product you've scanned, like your protein powder or yoghurt, and that part uses the figures from its label instead of an estimate. Many common foods use figures from Food Standards Australia New Zealand's food composition data. Each estimate also gets a high, medium or low confidence, based on how sure Frittu is of the amounts.

Checked against your allergen list

A photo of a cooked dish can't show every ingredient in it, so a dish scan isn't an allergen check. If an item on the plate is on your allergy list, Frittu points it out; for a packaged product, scan its barcode or ingredient label instead.

Why it helps

A list you can edit

Every estimate comes from the items and amounts you can see and change.

Label figures where you have them

Items linked to a scanned barcode use the product's own label figures.

Confidence on every estimate

High, medium or low, based on how sure Frittu is of the amounts.

Your past dish scans

They stay in your history, so you can look back at what you logged.

Dish scans and calorie estimates are included with Frittu Pro, which starts with 7 days free on the monthly plan, once per Apple ID or Google account. Calorie and macro figures are estimates, not medical or dietary advice.

Questions people ask

Is there an AI calorie counter app?

Frittu is a calorie counter app on iPhone and Android that works from a photo. Take a picture of your meal, check the items and amounts it lists, and log the estimate to your day. Scanned barcodes and the recipes you cook in Frittu log their calories too. Every figure is an estimate, not medical or dietary advice.

How do I count calories from a photo of my food?

Take a photo of your plate in Frittu. It lists each item it sees with an amount; check the list and correct anything that's off, then tap for the estimate. You get calories, protein, carbs, fat and fibre, and can log the meal to today in one tap.

How accurate is counting calories from a photo?

It's an estimate. A 2026 test of four photo-based apps on weighed meals found they came in 250 to 345 calories low on average, mostly on fat and portion size. Frittu shows each item and amount it saw so you can correct them before you log, and an item linked to a scanned barcode uses the label's figures.

What if it gets an item or an amount wrong?

Change it before you log. The list is fully editable: rename, add or remove items and change amounts, and the estimate follows.

Does it count macros too, or just calories?

Both. Each estimate includes protein, carbs, fat and fibre as well as calories, and a logged meal counts toward your day.
