We target operating systems >= Android 4.4 (API 19) and >= iOS 9.0.
- Support iOS and Android with one codebase
- Familiar web programming model (React + Javascript + Flexbox)
- Cross-platform, 90% code reuse between iOS and Android platforms
- Android: You can build and run with any of Linux, Windows, or macOS.
- iOS: macOS only. Many contributors use Linux or Windows and develop without testing on iOS. Fortunately, React Native means this works fine.
To become highly productive in working on Zulip Mobile, you'll want to set up your development environment in several ways:
- Building and running the app. See our instructions.
- An editor, or IDE, with good support for navigation and type information. This makes a big difference in productivity, and especially so when working in a codebase that's new to you. See our Editors / IDEs guide.
- Git. See our Git guide for a bit of setup, and some valuable tips you may not know (even if you've been using Git for a while).
- Debugging. It's fine to skip this at first to get going, but when you're tackling a moderately complex issue, a good debugging setup can help a lot. See our debugging guide for details, including setup instructions.
