Share apps during an IRL stream, stream mobile games, or broadcast tutorials and presentations straight from your phone. Your screen. Your stream. In your pocket. SRT, RTMP & RTMPS Stream to supported platforms, your own servers, relays or custom streaming setups. SRT is designed for reliable, low-latency streaming, while RTMP and RTMPS are widely supported by streaming platforms and servers. Simply enter your destination URL and stream key in pocketScreen. The app focuses on one destination per stream, keeping setup simple and fast. 720P OR 1080P SCREEN STREAMING Stream your screen using H.264 hardware encoding at 30 FPS. Choose between 720p and 1080p and adjust the video bitrate to match your connection. Portrait and landscape orientation are handled automatically. APP AUDIO, MICROPHONE OR BOTH Choose exactly what your viewers hear: app audio, your microphone, a mix of both, or no audio at all. Audio is streamed using AAC. LOCAL MP4 RECORDING Optionally save a local MP4 copy of your stream directly on your iPhone while broadcasting. Perfect for reviewing, archiving or reusing your content later — without running a separate recording app. START STREAMING THROUGH IOS pocketScreen uses the built-in iOS screen broadcasting feature.

MADE FOR IRL STREAMS, MOBILE GAMES AND MORE Share maps, apps and other on-screen content with your viewers while you're on the go.
