### 5/5 — Recommended

*2021-07-04*

I recommend this app if you need information on flying. Great app with great information that I can’t see myself getting anywhere else

### 1/5 — Rip Off.

*2020-09-24*

DO NOT BUY
There aren’t really any details as to what the in-app purchase gets you, and its kind of implied there’s videos for the checklist flows. 
Turns out, YOU have to record the flows. Could have done that before spending 20 bucks on the app :).
The AFM is free online, and I’m sure you can find a quizlet with the same or similar questions the quizzes on this app provide.

**Developer response:** Hi,
This app has manuals, flash cards, quizzes, memory items, systems questions, limitations, aircraft panels, schematics, and about 20 learn to fly publications for various pilot certificates and ratings. Please let us know what else you would like in the app.
Thank you,
Aircraft Apps Management
