Photograph your meal. Kaloro reads the calories and macros — and then lets you fix the two things every other AI calorie scanner gets wrong: the cooking oil and the portion.

A photo shows the food. It does not show the oil in the pan or the butter stirred in at the end, and it cannot tell a small plate from a large one. That is why a 900-calorie meal so often gets logged as 400.
This is measured, not asserted. Against meals weighed on a scale, the better two of three leading vision models (ChatGPT and Claude) produced a mean absolute percentage error of 35.8% for energy, and all models exhibited systematic underestimation that increased with portion size
(Fridolfsson et al., Current Developments in Nutrition, 9 September 2025). A second study of 114 meal photographs found the model named the food well — good precision (93.0%)
— yet underestimated 11 of 16 nutrients, with weight agreement fine on small meals and poor on medium and large ones (O'Hara et al., Nutrients, 7 February 2025).
The fat is the part no camera will ever see. Fat carries about 9 kcal per gram (the standard factor in FAO's food-energy guidance), so a single 14 g tablespoon of olive oil is roughly 126 kcal missing from your day (FAO, Food energy: methods of analysis and conversion factors, 2003).
And almost nobody in this category says so. In a scan of 79 iPhone photo-calorie listings on 24 September 2026, 2 of 79 mentioned cooking oil, butter or added fat at all, and only 1 offered a way to adjust for it. Method and the full table are on the comparison page.
One honest caveat before you expect miracles: human self-reporting is wrong too, and in the same direction. Against measured energy expenditure, an image-based food record underreported by 12% for men
and 10% for women
(Boushey et al., Nutrients, 22 March 2017). Kaloro narrows a range. It does not hand you a laboratory value, and a kitchen scale beats it on any day you are willing to use one.
Kaloro states what it assumed — "1 plate, about 400 g, normal oil" — and gives you two taps to correct it: cooking (light, normal, generous oil) and portion (small, normal, large). The number updates as you tap.
An estimate whose assumptions are visible can be fixed. A bare number can only be wrong.
Most scanners are trained on restaurant plates and packaged food. Kaloro knows home cooking — including Turkish dishes, which generic models routinely misread and undercount. Mercimek is logged as mercimek, not as "red lentil soup".
Kaloro will not set a target below 1,200 kcal for women or 1,500 for men, will not plan faster than 0.75 kg a week, and will not accept a goal weight under a healthy BMI. Those are limits, not suggestions. Kaloro is for adults only.
Meal photos are analysed and discarded. They are never stored on our servers. The photo lives on your phone and nowhere else.
Free to download. Logging meals by hand is free and unlimited, and you get one free photo scan a day for your first three days. Kaloro Pro is a weekly or yearly subscription; the weekly plan begins with a 7-day free trial. Before you start it, the paywall lays the trial out as a timeline: today, a reminder before it ends, then the first charge. Prices vary by country and are shown in the app and on the App Store product page before you buy. Cancel any time from your Apple ID settings.
Measured against food weighed on a scale, the better two of three vision models tested (ChatGPT and Claude) had a 35.8% mean absolute percentage error for energy, and every model tested underestimated more as the portion got bigger (Fridolfsson et al., Current Developments in Nutrition, 9 September 2025). On home cooking the cause is specific: the model cannot see the cooking oil, the butter stirred in at the end, or how large the plate is. Fat carries about 9 kcal per gram (the standard factor in FAO's food-energy guidance), so one 14 g tablespoon of olive oil is about 126 kcal that no camera records. Kaloro shows the assumptions it made — portion size and amount of oil — and lets you correct both with one tap, which is what closes most of that gap.
Yes. Every result carries a cooking chip (light, normal or generous oil) and a portion chip (small, normal or large). Tapping a chip updates the calories and macros immediately.
Yes. Mercimek çorbası, kuru fasulye, menemen, mantı, lahmacun, pide and karnıyarık are recognised by name, not as generic "lentil soup" or "beans". The app interface is available in English, Turkish, German, French, Italian and Spanish.
Kaloro is free to download. Logging meals by hand, your history and the weekly view are free and unlimited, and the photo scan is free once a day for your first three days. Kaloro Pro unlocks unlimited photo scanning, offered weekly (with a 7-day free trial) or yearly. Prices vary by country and are shown in the app and on the App Store product page before purchase.
A photo is sent for analysis and discarded in the same request. It is never written to a database, a file store or a log, and it is not used for training. Meal history stays on your phone.
No. Kaloro is built around the photo: you take one or pick one from your library. If you eat mostly packaged food with barcodes, MyFitnessPal or Yazio will suit you better.
Adults (18+) who cook at home and want a number they can trust rather than a number that looks precise. Kaloro will not set a target below 1,200 kcal for women or 1,500 kcal for men, will not plan faster than 0.75 kg a week, and will not accept a goal weight below a healthy BMI.

Claims on this page about photo-calorie accuracy, cooking fat and the app category come from published research and from measurements I ran myself and dated. Claims about Kaloro come from the app. Inside the app, a Sources screen lists the published method behind every number in your daily plan — Mifflin-St Jeor for resting energy, FAO/WHO/UNU for activity levels, the NIH guidelines for the calorie floor, and more.
