Dictionnaire Français.

I love this app. It is wonderful, I use it constantly. However the new adds are very frustrating. I’m not a deadbeat so I would gladly pay good money for this app to do without the adds, but to my chagrin, you don’t seem to offer that option. Please rectify this.

…but only a little. This app serves very well as a dictionary. The bit that could be improved is the way it displays verb conjugation tables. It shows all the grammatical persons at once, but this is the only tool I’ve ever used that makes you choose which tense and mood to show. Most just have a series of tables with person conjugations for each tense and mood. Maybe it’s cleaner this way, but using a drop-down selection on an iPhone is a pain. A set of radio buttons would be better.

This is by far the best free French monolingual dictionary app out of the six that I've tried. Some strong features: the search facility is very flexible, the definitions are assembled from a variety of sources, it gives synonyms and antonyms, and previous searches are saved so that you don't have to type the same thing over and over AND can conveniently review new vocabulary.
