But wouldn't knowing that require that you investigated the tech choices of all the apps you are using? If not, there's a slight fallacy in that you only _know_ that the app is cross platform when you can see that it is. So then obviously all the apps you know is cross platform will look out of place, because that's how you know they are cross platform. Not sure I'm making the argument very well.
For instance, I'm don't think that the Discord app for iOS and Android looks out of place [0].
> Switching to React Native for the Android app means an experience that is ever-improving at a more rapid pace across every platform Discord is available on, while still retaining Android and iOS specific patterns in the UI.
