Great overall, just a couple of thoughts
So far I’m really enjoying the free trial for this app, and am highly considering a subscription. However, I have noticed that a few of statements regarding casual expressions and slang don’t always take into account Québécois French. E.g. the app specifically pointed out that no one would ever say « bon matin » to say « good morning », and that this expression does not exist… But « bon matin » is commonly used in Québec, so it might be nice to include that instead of saying it does not exist anywhere. I also get though that including all of these differences would be a huge task.
