Don't have a production app, but i am developing a mobile app for a existing service. The app is very simple at the moment. App loads remote data and uses aysnc storage as well. I don't have Android exp except for tutorials. Getting to understand the React Native framework took some time but then its very straight forward easy process(Just Android app, have not tried out iOS). I do have good React exp which helped. For simple app it seems a very good solution.
