Photo Log Scale Calibration
Photo log scale calibration matches one weighed meal to its image weekly so repeat photos inherit your real portions—not generic database defaults.
Photo log scale calibration pairs one weekly weighed meal with its photo so the app learns your plate size, rice mound, and chicken portion visually—reducing drift on repeat lunches. Photograph the same plate empty and full once; save as a personal reference.
Calibration beats trusting generic database portions for dense carbs.
Common questions
-
How often should you calibrate photo logging with a scale?
Once per week on a repeat meal is enough for most people—more often if you change plate sizes, cook new staples, or see macro drift on identical photos.
