Proper application

* A dictionary of 90,000 words (only)
* More than 135 000 definitions with all nuances of meaning
* 140,000 synonyms, homonyms and contrary
* 34,000 words and phrases formed with the word
* 9000 citations of French and foreign authors
* 6000 practical items to avoid the pitfalls of language (spelling, grammar, pronunciation, difficult conjugation, shades of meaning, good use ...)

However, the application requires access to location history without any reason and despite its price, as well as access to shared files, access to oral pronunciation (audio) is through access to the Internet, and the interface is not very nice and not configurable (font size, for example), and the definitions are (too) brief.
BlackBerry 10 (Z30 and Z10) application is fairly fluid.
The application is downloaded quickly but in two steps and takes less than 12MB of storage space.
