Zulip Mobile (legacy, unsupported)

This codebase built on React Native is an unsuppported legacy app. On 2025-06-07, we launched a new Zulip mobile app with Flutter.

This repository will be archived soon; see https://github.com/zulip/zulip-mobile/issues/5931. If you're interested in contributing to Zulip's mobile apps, see zulip-flutter.

Details below are from when this app was in active development. Some details may still be useful, but bear in mind that this legacy app is unsupported as described above.

Discussion

To get involved in Zulip Mobile development, please join us on the Zulip community Zulip server, in the #mobile-dev-help channel. Come say hello, discuss areas to work on, and ask and answer questions.

Bug reports and feedback from using the app are welcome. For those, please use the #mobile channel; that helps a wider set of Zulip contributors see your feedback.

Using the beta

One important way to contribute is to run beta versions of the app, and report bugs! To get the beta:

• Android: install the app, then just join the testing program on Google Play.
  • Or if you don't use Google Play, you can download an APK; the latest release on GitHub (including "pre-releases") is the current beta.
• iOS: install TestFlight, then open this public invitation link on your device.

Bug reports are welcome either in the #mobile stream or on this GitHub repo.

Development

Zulip Mobile is written in JavaScript with React Native. To get started with the code, follow this doc:

• Developer Guide

Then see our Contribution Guidelines, and come say hello in the #mobile-dev-help stream.

For more reading, take a look at our developer docs.
