Looking for feedback on my new app!

Hello, I just built a app for student pilots looking to learn ATC. I just published and I need a few users just to start out with before I setup stripe. I am not pilot approved yet I will get it very soon. The app name is ATCpal. I am looking for some feedback if possible.

Even if you don’t know how to talk to ATC like I said I am just looking for feedback! Thanks so much I hope you guys can help me!
