"Restaurant Nutrition" is one of the worst executed, most pointless apps in the entire app store. Let's start with the premise: the app is designed to show you the "nutritional value" of meals in fast food chains such as Arby's and Burger King. Note to reader: if you are interested in nutrition, avoid fast foods. Keeping track of your trans fat intake with "Restaurant Nutrition" is not going to do your body any good.
But leaving aside the premise, this app fails on almost every level. First of all, to really use the app, you are required to create an account on a site called "thePHRNetwork.com" -- which, incidentally, is not currently open for new accounts. Then, to add insult to injury, the app keeps asking you for a PIN which you never created in the first place. Finally, the app has a tendency to randomly crash.
