The most popular Android app that I know of that uses RN extensively is Discord. Read the reviews here as the start of the answer to your question - https://play.google.com/store/apps/details?id=com.discord

RN works great for CRUD apps. But do you really want an app if it's only CRUD? Might as well just make a site or some PWA.

With a lot of apps, you end up dealing with something lower level e.g. EXIF data, bluetooth networking, things like custom calls through the app built on the native call kits.

Plus finer control on the UI & lifecycle. Something like Compose/XML or even Flutter/Dart is built perfectly for mobile interfaces, while with RN it feels like you're wrestling with flexboxes originally designed for desktop. RN supports this stuff, but then you'd still have to learn Kotlin and Swift, so it's not exactly a free ride.

Kotlin Multiplatform lets you share code between iOS and Android, writing only the UI code with SwiftUI and the rest is shared. You can also run Compose UI on the desktop so you don't need a web app.

KMM is also in alpha so I wouldn’t recommend using it in production.

I will use React Native when it reaches v1.0.
