Joke- you would feel foolish if you used this very informal...
Like most language's, their is a common/ casual way to speak and a proper way to speak.
French, the language, may have the allusion of being Le même, the same , but, when I spoke with a person from Quebec, I believe they call them Québécois, they , in they say things so differently than France.
The French do not use the word Je to describe inanimate situations. There are feminine words and masculine words. Every word in French is either or , further you have to know which one it is plus who you are speaking which adds to the mixture of a proper sentence.
This app is a data dump.
The tutor also isn't french, and lacks the depth and nasal inclusions along with pronunciation of speaking.
I truly believe their is nothing in America , unless L'ecole ou L'Universite ( and I wonder if that I used the masculine noun correctly ) pardon moi, not excusé moi, will French. Try an erudite or a Parisian.
Otherwise, I highly doubt using French after studying it and then you visit , they will call your attempt to speak it just, "necessary ". Not good. Bottom line, don't use/ bother with this app at all. Free is used for a raisôn.
