StreamToVR · iPhone
Live in 3D.
Your iPhone has two back cameras. StreamToVR turns them into one live 3D camera and streams VR180, 360 stereo or side-by-side 3D to YouTube, to your own RTMP or SRT server, or straight to a VR headset on your Wi-Fi.
Coming soon to the App Store
iPhone with ultra-wide and wide back cameras · iOS 26 or later

Two cameras, one stereo camera
StreamToVR films with the ultra-wide and the wide camera at the same time. The ultra-wide is cropped to the wide camera's field of view, the two cameras are kept in step on exposure and white balance, and every pair is aligned on the GPU from the iPhone's own factory stereo calibration — in about 3 ms per frame. The ultra-wide becomes the left eye, the wide the right.
Stream it anywhere
- YouTube Live over RTMPS with Enhanced RTMP and spherical metadata, in standard 16:9 frames up to 2160p.
- Your own server — RTMP, RTMPS or SRT with stream ID, passphrase and latency — for MediaMTX, OBS, vMix, nginx-rtmp and the like.
- A VR headset on your Wi-Fi — the iPhone serves a WebXR player itself. Open its address in the headset browser, for example on Meta Quest. No internet and no account needed; works over Personal Hotspot too.

Built for going live
Live captions are recognized on the iPhone in your language and sent to YouTube, to the headset, or burned into the picture. A dropped connection retries by itself, video pauses rather than stutters when the network falls behind, and a statistics panel shows frame rate, bitrate and the state of every stage.
