Talks about: React Native Playground
Important to get stuff out there (easily).
Inspired by @vjeux who wished there was a JSFiddle like experience for React Native.
appetize.io provided a free emulators for React Native.
Future: Test on real devices, not in the browser.
app.reploy.io let your users test your app, make screenshots and provide feedback, all in the browser.
Future supporter and tool to use: reindex.io
