QuestionsBefore we start
Do you build for Android too?
React Native and Expo apps run on both platforms. My published apps are on iOS, so tell me if Android is part of the launch and we will plan testing for it.
Will you handle App Store submission?
Yes. I set up the build and submission pipeline and take the app through review.
