This is the best iPhone and iPad French-English dictionary available. First, it is a solid bi-lingual dictionary. (The best dictionary was Harraps, but that is no longer available on iOS. Its only available in hardcopy.)
The rewrite of the app has taken some of the great features of the companys other Ultralingua app and applied them here. In particular, I really appreciate the ability to change the font size. Also, the app is pretty quick to find words. Great job!
