A waste of 9.99 and I will be asking for my money back. The scenario based questions could potentially be the most useful, but you cannot get the enroute charts to open, making them impossible to answer.

Edition 10 has been out since at least early 2020, yet this app isn’t updated. Are we supposed to shell out another $10? Even if I attempted to buy the updated edition, the app still brings me to download the previous 9th edition.

The regulations questions are mostly OK. Many scenarios are out of date and no longer reflect current airspace, routes, minimum altitudes, etc.

You can mark questions for review but theres no tracking of study sessions to see how well you're doing. You just have to select a section and wade through its questions aimlessly. I think this could be a great app if they added the ability to track your progress. Would be very helpful to have an option like "Study X questions ordered by least studied" and "Study X questions ordered by hardest (questions you keep getting wrong)".
