Spancam turns the iPhone in your pocket into a sharp, reliable webcam for your Mac with advanced AI Features - over your Wi-Fi network, with no clutter. Your iPhone almost certainly has a far better camera than your Mac's built-in webcam. Spancam puts that camera to work for video calls, streaming, and recording. HOW IT WORKS 1. Install the free Spancam desktop app on your Mac. 2. Open Spancam on your iPhone and make it discoverable on your Wi-Fi network. 3. Your Mac finds your iPhone automatically — accept the connection. 4. Pick "Spancam" as the camera in Zoom, Google Meet, Microsoft Teams, FaceTime, OBS, or your browser. That's it. WIRELESS, THE EASY WAY • Leave the cable behind — stream over your local Wi-Fi network. • Your iPhone is discovered automatically; no IP addresses to type. • Automatically reconnects if the connection drops. BUILT FOR REAL CALLS • Smooth, low-latency, hardware-encoded video (H.264 and HEVC). • Front or rear camera, with a clean on-phone viewfinder. • Pro controls: zoom, exposure, focus and white balance. • A live status indicator shows when you're streaming, with signal strength and bitrate. PRIVATE BY DESIGN Spancam has no accounts, no ads, and no trackers. Your video goes only to your own devices, over your own local network — never to us, never to anyone else. Nothing is uploaded. REQUIREMENTS • iPhone with iOS 17.0 or newer. • The free Spancam desktop app (macOS available; Windows and Linux on the way).
