Hotwire Native tbh wouldn't have been a bad choice at all to use tbh. Especially if you wanna maintain 1:1 parity with the website. It combines both being a "web app" and native features we could still use like Tap to Pay and Push Provisioning. The downsides of it is that it isn't a cross platform framework like React so all changes would have to be pushed to both an iOS app repo and an Android app repo. Another downside is that it isn't a "write once run anywhere" type application as you're integrating Hotwire into the native code so you have to be comfortable with both Kotlin and Swift (however if you're writing native modules in React Native same applies).

Both are 2 completely valid and separate paths you could take when building an app and I'd actually be curious what'd HCB Mobile look like if we did use Hotwire Native.
