This app is terrable, when i first downloaded this app i was excited to learn spanish with the coarses of thia app. But then i got some thing wrong and easly replenished the hearts, but then the second time i did not have enough, making it so that i would have to wait hours for just one heart. Also just that that would take months for it to be replenished, and by that time i woupd have forgotton all of the stuff si then i would not evan understand. And the only good thing is that it is easy.
