Here are a few I've found, I was wondering if anyone one has had experiences with any of these:

- Kitten UI: https://akveo.github.io/react-native-ui-kitten/

- Ant UI: https://rn.mobile.ant.design

- RN Paper: https://reactnativepaper.com

- React Native Elements: https://react-native-elements.github.io/react-native-elements/

- Shoutem: https://shoutem.github.io/docs/ui-toolkit/introduction

- NativeBase: https://docs.nativebase.io/

Interested to hear personal experiences with these libraries or others that I have not included.
