Every calorie number you have ever seen in a tracking app is an estimate. The database entry is an average across samples. The portion is a guess. The cooking method is unknown. None of that stops most apps from printing a single confident figure.
The cost of false precision
When an app says 612 kcal, you believe it to the digit. When it's wrong by 150, you don't find out — you just slowly lose trust in the whole system and stop logging. False precision doesn't make tracking easier; it makes the eventual disappointment sharper.
What we do instead
MealLens shows a match confidence alongside every scan. High confidence means the dish was unambiguous and the portions read cleanly. Lower confidence means something was occluded, unusual, or hard to size — and it's an invitation to adjust rather than a failure.
The goal isn't to be right every time. It's to be honest about when we might not be, so the number you log is one you actually believe.
