Picture calorie trackers are usually only moderately accurate because photos cannot reliably show portion size, depth, or cooking methods. These missing details often lead to incorrect calorie estimates.
Most picture calorie trackers provide rough estimates rather than precise values. Accuracy varies depending on food type, portion size, and image quality.
Photo tracking can help build awareness of eating habits and works best for simple, single-ingredient foods.
Some users switch from photos to short meal videos, which provide more context. Video-based tracking tools like Powtain aim to capture portion size and food details more reliably.
