A note on accuracy
Every photo calorie tracker, including both of these, estimates portion size from a single image. That is fast but imperfect — check the portion of calorie-dense foods such as oils, nuts, rice and sauces before you save. We have not published a head-to-head accuracy test yet and won’t quote accuracy figures until we do.
