Hated it. They don't really teach you anything. They just ask you to fill-in questions or write something in French, and they're testing you on things that no one's ever taught you. So there are words you've never seen before. And then when you get it wrong you can't go on because you've made a mistake and you have to buy hearts. Everything's about trying to get you to buy hearts. I hate only learning by having to guess and I must get it right in order to keep going. It seems a very negative reinforcement kind of way to run a learning app. And it doesn't work for me at all. I was trying it out to see if I liked it and then I would've paid to join, but it was just irritating and useless.
