 Jitsi Meet is an open-source (Apache) WebRTC JavaScript application that uses [Jitsi Videobridge](https://jitsi.org/videobridge) to provide high quality, scalable video conferences. You can see [Jitsi Meet in action](http://youtu.be/7vFUVClsNh0) here at the session #482 of the VoIP Users Conference.

+# Jitsi Meet mobile apps
+
+Jitsi Meet can also be built as a standalone mobile application for
+iOS and Android.  It uses the [React Native]() framework.
+
+First make sure the [React Native dependencies]() are installed.
+
+**NOTE**:  This document assumes the app is being built on a macOS system.
+
+**NOTE**:  The app must be built for an actual device since the simulators don't
+work properly with the native plugins we require.
+
+
+## iOS
+
+1. Install some extra dependencies
+
+  - Install ios-deploy globally (in case you want to use the React Native CLI
+    to deploy the app to the device)
+
+    ```bash
+    npm install -g ios-deploy
+    ```
+
+2. Build the app
+
+    There are 2 ways to build the app: using the CLI or using Xcode.
+
+    Using the CLI:
+
+    ```bash
+    react-native run-ios --device
+    ```
+
+    When the app is launched from the CLI the output can be checked with the
+    following command:
+
+    ```bash
+    react-native log-ios
+    ```
+
+    Using Xcode
+
+    - Open **ios/jitsi-meet-react.xcworkspace** in Xcode. Make sure it's the
+      workspace file!
+
+    - Select your device from the top bar and hit the "play" button.
+
+    When the app is launched from Xcode the Debug console will show the output
+    logs the application creates.
+
+
+3. Other remarks
+
+    It's likely you'll need to change the bundle ID for deploying to a device
+    because the default bundle ID points to the application signed by Atlassian.
+
+    This can be changed in the "General" tab.  Under "Identity" set
+    "Bundle Identifier" to a different value, and adjust the "Team" in the
+    "Signing" section to match your own.
+
+
+## Android
+
+The [React Native dependencies]() page has very detailed information on how to
+setup [Android Studio]() and the required components for getting the necessary
+build environment.  Make sure you follow it closely.
+
+1. Building the app
+
+    The app can be built using the CLI utility as follows:
+
+    ```bash
+    react-native run-android
+    ```
+
+    It will be launched on the connected Android device.
+
+
+## Debugging
+
+The official documentation on [debugging]() is quite extensive, it is the
+preferred method for debugging.
+
+**NOTE**: When using Chrome Developer Tools for debugging the JavaScript code
+is being interpreted by Chrome's V8 engine, instead of JSCore which
+React Native uses.  It's important to keep this in mind due to potential
+differences in supported JavaScript features.
