What you actually get
Most calorie apps sell a database and leave you to search it. Here is the specification.
InputOne photoThe plate, from above, in ordinary light. The photo is read and then thrown away. We keep the numbers, not the picture.
OutputMacros, item by itemEach food named, with a portion in grams, then calories, protein, carbs and fat. Plus a one-line note when the photo is hiding something, like oil or a sauce.
SpeedWhile you are still at the tableThe read comes back in a few seconds. There is no person in the loop and no email to wait on.
LogYours for the plan you boughtMonth, quarter or half year. The half-year plan adds a weekly total of what you actually logged, not a meal plan someone else wrote.
