We ran the exact same code (minus the Chat view) that we have on iOS which performs really well. It performed poorly on Android devices we care about. Touch events would lag (because of the JS computations hey resulted in), animations would be choppy (Android has native Animated.js now though, we haven't tried it). Our conclusion was since we already had a pretty good native Android app it was probably not investing time in a degraded experience. We will maybe try again in the future but the gut feeling is JS performance on many slow cores (Android devices love this) is obviously not as good as two fast cores (iOS devices).
