I wanted to develop a student app that possibly could be used by many teams (students from other schools)

I chose Ionic, because:

single codebase: previously, we used React Native for Android and Angular for web/PWA, which was troublesome
portability: runs on PWA (which is important, because iOS license is too expensive for school app), web, Android iOS (+ others, if needed)
full use of web technologies: Next.js, Tailwind, React in this example (in oppose to Flutter/Java/Kotlin)
stability and maintainability: low-entry level due to basic web technologies without new syntax (in oppose to React Native and Flutter), web is really stable and won't lose support (which doesn't have to be true with Flutter/Dart)
