Way to start focusing your intake on some great metrics. All three of those items are key, especially related to heart health. Lose It is one app which does separate saturated fat from total fat if you click into "My Nutrients". I'm not aware of one that separates added vs natural sugar (this is unfortunate, but perhaps because that is a newer change in food labeling). Weight Watchers (WW) uses a points systems, though it does display a full label for each food, including different fats and added vs. natural sugars. Is there an app you are more comfortable with?
