This is a great app. Its worth the 3.99. Its great for tracking protein just like it says. It also keeps track of calories, fat, carbs, sugar, etc in grams. I WISH they would ADD a pie graph that shows the percentage of each type of calorie consumed (example:40% protein, 20% fat, 40% carbs)- then it would be WAY awesome..... So for now only 4 stars!
