First, it always gives a calorie count for cooked meat, but it should assume the meat is uncooked since I said it was for a recipe.
Second, it seems to struggle with the concept of uncooked rice. If you ask it to work with 1 "rice cooker cup" of rice, it refuses because that isn't a standard measurement. If you swap in the converted standard measurement (3/4 cup), it still is way off. It told me 3/4 cup uncooked rice is about 150 calories when cooked. That's a third of what the USDA database gives. When you point out that 3/4 cup uncooked rice is a large serving after being cooked, it changes its answer to 375 calories, still about half of what the USDA database gives. But this is fine for me because rice is not typically part of my recipes since it doesn't usually require special preparation.
Overall it reduces a 10 minute task to 10 seconds, but you need to know enough about the ingredients to spot obvious problems in its result. In my case I could see the calories given for meat was way too high, and way too low for rice. It gave a better answer after telling it to fix the former and ignore the latter.
I tried a second recipe and the total it gave was 2% under my calculation, but I did not see any obvious error in its result so I could not correct it further.
It is unfortunate that you kind of have to trust the numbers are correct, but this is no different than the nutrition details on sites like MyFitnessPal which are often wrong when you closely examine it.
