Every calorie number you have ever logged was an estimate. This one admits it.
A photograph is not an accurate way to count calories. Neither is a person looking at the same photograph, or a database entry for a food that varies, or a weighed log that leaves out the frying oil. Snapkin shows you which part of the number it is confident about and which part it made up.

The published numbers, including the ones we would rather not print
These are not our figures. They are what the literature reports for vision models estimating meals from photographs, and the page they are argued out on is linked at the bottom.
A photograph is not accurate. Neither is a person looking at the same photograph. Nobody is choosing between this and a perfect log. They are choosing between this and no log at all. What the research does show is where the error lives: recognising the food already runs at 74 to 93%, and portion size is the bottleneck. So the app asks you a question back instead of handing over a total, and writes down what it assumed.
A photo gives a good guess, not a lab result. Snapkin says which is which.
Every ingredient shows the assumption behind it, and the meal says how sure it is overall. When it is guessing, it says so. When it is wrong, you say so, and it shows the before and after.
The meal carries a confidence.
Best guess, or mostly assumed -- a summary of how much of the plate it could see and how much of it it had to work out.
Each ingredient carries its assumption.
"A whole fillet, sized against the plate." "Seared in about 8 g of oil, folded into this line." You can see the sentence that produced the number.
It names its biggest unknown out loud.
Usually the cooking fat, sometimes the portion. That is also the question it will ask you, and answering it is the highest-value thirty seconds you can spend on a meal.
Correcting it shows the before and the after.
Say the portion was smaller, or that it was fried in butter, and the meal redraws with the change marked. Every correction is undoable and every one of them is also something it learns.

That is the whole habit, and it survives restaurants, holidays and Thursdays, because there is nothing to keep up.
