DualCast Live

DualCast Live is a professional live streaming app built for one unique purpose: broadcasting from your front and rear cameras at the same time. Most streaming apps only let you use one camera. DualCast Live composites both feeds in real time, so your audience sees more of the story as it happens. CONNECT TO ANY RTMP SERVER Configure YouTube Live, Twitch, Facebook Live, or any custom RTMP/RTMPS endpoint in seconds. Save up to 10 server profiles and switch between them with one tap. Stream keys are encrypted with AES-GCM and stored only on your device. DUAL-CAMERA COMPOSITING MODES Choose how your front and rear cameras combine before you go live: - Split View: side-by-side layout with an adjustable split ratio - Overlay Blend: adjustable opacity blend between both feeds - Perspective Merge: perspective-corrected overlay for matching horizons - Dual Exposure: cinematic double-exposure style blend - Frame-in-Frame: picture-in-picture with a movable, resizable inset PRE-STREAM CONNECTION CHECK Run a 4-step network and server check before you go live, covering network type, TCP connectivity, RTMP service response, and port/firewall status, so you catch problems before your audience does. RELIABLE, LOW-LATENCY BROADCASTING Built on a hardware-accelerated AVFoundation and HaishinKit pipeline targeting under 300ms end-to-end delay, with automatic reconnect if your connection drops and a live stats overlay showing bitrate, duration, and CPU load. RECORD WHILE YOU STREAM Simultaneously save a local MP4 recording of your composited broadcast while streaming live, so you always keep a backup copy. PRIVACY BY DESIGN DualCast Live requires no account, no login, and no cloud sync. RTMP server addresses and stream keys are encrypted and stored only on your iPhone. The app does not collect or transmit your personal data. ONE-TIME PURCHASE DualCast Live uses a simple one-time purchase model. The base app is fully functional for streaming. Premium unlocks additional compositing options and quality settings, with no subscriptions and no recurring fees. Requires an iPhone with a rear and front camera and a stable internet connection. Streaming quality depends on your network conditions and the receiving RTMP server.
