Poor app.
About the only good thing that I can say about this app compared to the GroundSchool app that I ended up mostly using is that this one cost less. other than that, I found it pretty buggy .. For example, when you click on "grade" it gives you a box "do you want to grade" but only one choice essentially.. Yes. Howeve,r the biggest problem is the explanations. They are generally little more than restatements of the correct answer, and none are illustrated, its particularly bad for flight planning questions.. Its basically impossible to learn those, weather, weight and balance, and performance questions since the explanations are so meager. This app is clearly aimed only at those who want to memorize, not learn.
