This app is very limited. All the calculator does is tell you how many carbs, proteins and fats you should have daily. It does not track your daily intake so you can adjust your meals! MyNetDiary is much superior to this app even though it is not for a ketogenic diet. It gives you percentages of fat/protein/carbs. You can scan barcodes and enter any food.
