Yes, it's ridiculously easy on Android Studio. You can drag and drop interfaces lol. What would take 10 seconds in Android Studio takes 5 hours of CSS and 2 weeks of testing/debugging on the web. What is impossible or requires esoteric hacks on the web (concurrency) is done on mobile the exact same way it has been done for decades in software engineering (multithreading, CSP, ...) with entire books and college classes about how to do it.
