Requesting feedback for my first full app, FlyLines

Hello everyone.

I would really appreciate any feedback or critiques of my first full app, FlyLines.
The app is supposed to be a simple flight logger, mostly catered towards those who fly frequently.

the app features a flight adder page, a profile page with flights and statistics from those flights, a network map of your completed routes, an airline page with all airlines that are featured and a badges page with some achievements for frequent flyers and others.

The app is free on the App Store and is not currently available on Android devices.

I wanted to make the app fully functional without an internet connection or cellular data (such as in a plane).

Thank you.
