Tethr - Phone Webcam
Turn your Phone into a webcam
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
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
Install the free Tethr app on your Windows PC
Open Tethr on your iPhone
Connect your iPhone to the PC with a USB cable and tap "Trust This Computer"
Select "Tethr" as your camera in OBS, Discord, Zoom, or any other app
That's it — your iPhone camera is now your webcam.
PRIVACY
Tethr is built to keep your video yours. The image travels directly from your iPhone to your own computer over USB. Tethr does not run servers, does not upload your video, and does not sell or share your data. See our Privacy Policy for details.
