A great study tool, an excellent refresher!
Used this app to study and prepare for my instrument written (passed with a 90% score). Its nice to be able to choose blocks of questions on specific topics, but this app shines when it comes to taking complete practice tests. 4 stars because some practice test questions do not allow you to access the appropriate figure needed to answer the question (IIRC it was on the minimum rate of climb questions). I took many practice tests with this app right up until my check ride, and I really think keeping all the info fresh in my head made the oral portion of the test easier.
