Wow, three languages is incredible. I think you are right, if you want to learn any language well you have to get in there and immerse with speaking it. The app is helping me with my vocabulary, but I need to get in speaking practice more. I have started my lessons now, so I'm hoping to make more progress.

Though there is lot about the french language that just doesn't make sense to me, which makes it so much harder.

I will get there one day.
