Frequently asked questions
Can one codebase run on both Android and iOS?
Yes. That's the main advantage of React Native: one codebase ships to both platforms, which saves time and budget.
Can you also build the backend for my app?
Yes. I'm a full stack developer, so I can build the API, database and admin dashboard behind your app.
