## Most critical reviews (2 lowest-rated)

### 2/5 — Missing reference diagram

*2023-02-09*

30% of the questions in this app referred to a diagram or a picture that illustrating the question before answer.
The app doesn’t show any of those illustrations, making it useless!

### 3/5 — Just okay

*2019-01-11*

It’s just OK. I mean, it is something to look at and study when you’re on the go, but do not use this app solely for your study material. If you use this app and back it up at the regular ATP written book, then I’d say you’re good.

**Developer response:** Thank you for your review. Our goal is to provide the question and answer choices to pass the written test with the highest score possible in the shortest amount of time. There is no substitute for studying official FAA textbooks and Advisory Circulars alongside instruction from flight instructors and aviation institutions.
