This app is crap because I need to force close it every 10 words or so and restart it because it stops responding to me. Also there are way better apps out there that one can use to learn French, like duolingo or memrise. And these apps actually explain what you did wrong and it also explains grammar. I hate that this app forces you to do 150 words. There is no customization of goals. Like 150 is a lot of words for a beginner. Even if you are repeating them. Its too much and far too overwhelming. Also this app is only good for learning how to read and listen. It doesnt teach you writing and speaking. So if you want to passively use French then I guess this is a great app for you.
