I wish all apps were this good
Shortly after buying my iPhone two years ago I bought the Ultralingua Portuguese-English dictionary app for it. Although I was hesitant given the price, it turned out to be a well-spent $20. The dictionary quality itself is as good as a medium to large-sized dictionary (not as good as the two-volume reference dictionary I have), but the UI is what makes it worth it -- making it easy to switch between definitions and verb conjugations -- everything is linked the way you want it to be. And they have made regular updates to the app as needed. When I bought my iPad, I was very pleased that they turned their dictionaries into "universal" apps so it had a special UI for the iPad without requiring a separate purchase. I cant recommend this app enough.
