Yea, I'm sure they have some pretty strict regulations with that kind of stuff. Turbo Native has come very far with integrating with hardware so you can use all of the hardware components that you need to, but you also would have to create the iOS app and Kotlin app. But it's still a lot less work than a React Native app or a standalone app. Hybrid is the current flavor of the "rails way". However, if that isn't an option to go hybrid due to requirements or policies, then React Native, Xamrin or similar could still be an easier route than a standalone Android and standalone iOS app.
