Congrats! This is really no small achievement, being able to make a profit while making mobile apps is no little thing.
I saw your comment that you made the app in Flutter, how come that you didn't release it then for Android?
Also a separate question, I do wonder what was your thought process for coming up with the idea for the app? Do you keep somewhere a list of app ideas, or was this one you have been dreaming about some time?
I'm using the Cupertino widget to have an iOS look and feel. I care a lot about the experience and I didn't want to release an Android app that feels like an iOS one.
That being said I'm almost done making the app look great on Android. I'm just waiting for some Material 3 widgets to be done by the Flutter team.
My thought process was simple : I don't like any of the apps on the App Store for 5/3/1, so I'm going to make my own!
I personally would argue that shipping (and being available) > than purely looking like it's 100% platform specific. But it's your app, and congrats on the success so far.

Keep going and I wish you much more success!
