I have a question. How would you know when you're using an iOS or Android app developed with React Native? Is it possible that you're only unimpressed when you actually notice something is off?
Because, in my experience, React Native is the first framework that actually feels native, and often results in apps that behave identically to their native counterparts. One of the big reasons for this is that it actually is using native components in most places.
Facebook's philosophy isn't that you should write platform-agnostic components and use them everywhere. They actually encourage using platform features wherever possible, but at the same time the way you write the components doesn't change across platforms -- "learn once, write anywhere."
