Almost perfect!

This app is so fun and easy to use, Ive learned so much in the short time that Ive used it and Spanish class is way easier for me now. It lets you set a reasonable goal that gives you motivation to practice for at least a few minutes every day.
However! There are a lot of really annoying aspects of this app that make it frustrating and bothersome. First of all, the concept of health is fine - it motivates you to go back and refresh old skills if youre going too fast and messing up on new ones. However it takes ridiculously long to recover because they need a way to get you to watch ads. Also theres only five lives, which is also ridiculous - mistakes happen and learning new skills takes time and patience, so five mistakes shouldnt set you hours behind on practice. Another annoying thing is how fast you lose skill bars - its insane! Time I could use learning new skills is wasted "strengthening" ones I already know.
Clearly there are a few issues, but overall I love this app. I use it every day and my Spanish has gotten so much stronger because of it. Would highly recommend to anyone, although Id encourage an update as well!
