Is it true that Discord android app is made with React Native?
The Discord iOS app is written in React Native but their Android app is not. From a blog post on 2018-07-26: "Similar to iOS, we tried React Native the day it was released for Android. We were surprised by how easily and quickly we were able to make our comprehensive iOS app run on Android — took only two days and it built! However, we immediately stopped after identifying various issues such as poor performance of touch events and lack of 64-bit support. We continued to follow React Native Android through observing many other apps and blog posts, but there have been no fundamental improvements to convince us to try again."
Look it up.
