Not sure if anyone might find this useful, but I found this site yesterday.
It seems very useful for keeping track of calories and displays a pie graph for Carb/Fat/Protein % based on what you've eaten or plan to eat. It also keeps a history of your days so you could track changes in caloric amounts or % of calorie distribution over time.
It has a search bar for instantly looking up foods and has a drop down tab for selecting amount of food, then you can add it to your daily food log.
I find it easier to eat or not eat items when I can see on a pie graph that for example my fat % is already good for that day but I need more protein or carbs to maintain my intended % and or total calories.
Anyways here is the link:
