Ask HN: Experiences using React Native

For those who've adopted RN I have a few questions based off your experience.

1. Were you able to keep to a single codebase across the different platforms you support?

2. Have your users experienced any UX issues?

3. Have your users experienced any power issues? Have they noticed your app draining the battery?

4. If you had the chance to start over would you use RN again? Why or why not?

Myself and the HN community really appreciate your feedback and experiences!
