Tethr - Phone Webcam

Use your iPhone as a high-quality PC webcam over USB. Low latency, up to 4K, works in OBS, Discord, Zoom, and your browser. Requires the free Tethr Windows app.

Tethr turns your iPhone into a high-quality webcam for your Windows PC.

Your phone already has one of the best cameras you own — far better than most laptop or USB webcams. Tethr lets you use it for video calls, streaming, and recording, connected over a simple USB cable.

IMPORTANT: Tethr requires the free Tethr companion app for Windows. This iPhone app sends your camera to the Tethr Windows app, which makes it available to your other software. A Mac version is not available yet.

WHY TETHR

Studio-quality video — use your iPhone's camera instead of a grainy built-in webcam Connects over USB — no shaky Wi-Fi, no network setup, no accounts Low latency — smooth, responsive video for real conversations Up to 4K — an optional high-detail quality mode Private by design — your video goes straight from your phone to your own PC. Nothing is uploaded, stored on a server, or shared

WORKS EVERYWHERE ON YOUR PC

Once connected, "Tethr" shows up as a normal camera on Windows, so you can select it in the apps you already use:

OBS Studio — for streaming and recording Discord — for video calls Zoom, Microsoft Teams, Google Meet Your web browser Any app that uses a webcam

FULL CONTROL

Fine-tune your shot from the Tethr app on your PC:

Flip and rotate the image Digital zoom, with click-and-drag to choose the crop Brightness, contrast, saturation, and sharpness Choose 1080p for the lowest latency, or 4K for maximum detail

SIMPLE TO USE
