The tracker has a pretty extensive library of both foods and exercises. According to the makers, it holds over 450,000 foods and 2,000 exercises. You can find what you want with an easy to access search field, and lets you toggle between different tracking screens with the buttons on the bottom of the screen. Information is displayed or simple line graphs, which are great for instant clarity with just a glance.
The only major gripe that this reviewer has with this application is the lack of available customizations. There is no “favorites” section for you to save commonly eaten foods to in order to save the user time. In addition you can not add any custom foods to the listings. This means that if you have odd tastes you may end up manually entering the contents of your peanut butter, marshmallow and chocolate sandwich on whole wheat bread. For the most part this app is good enough to use on a day to day basis and probably the most comprehensive tracker for your iPhone on the market today.
