I believe the iOS app for Phoenix Wallet is KMP and they’re in the process of transitioning the Android app to it.
Discussion
Nice. Interesting that they went in that direction (iOS first then android). I can see how that might be a good forcing function to get the layering/modularity right.
I think they first wrote the Android app, but it was written in Java and not made for KMP
Then wrote iOS app in KMP, now working on bringing Android version to use KMP as well.
