I already speak French having been an immersion student in the 1960s but my vocabulary is rusty after many decades of non-use. What I was looking for was an app that didnt assume that I was a beginner trying to learn the language. This app fits the bill with a solid word count, plenty of usage phrases and a smooth user interface on the iPad.
I do wish it was possible to search beyond just the dictionary entries. For example, being able to search for two word phrases such as "wrong turn" in the usage entries would be of great value.
