NMX Viewer streams your iPhone screen live to nmxviewer.com. Start a broadcast in one tap, open the page on any computer, and see exactly what is on the phone, with sound, in real time. Built for screens that stay on: a broadcast can run for hours or days, and NMX Viewer keeps it alive for you. LIVE, WITH LOW DELAY • Your screen appears in the browser almost instantly, so what you see is what is on the phone right now. • App sound is streamed together with the picture, and you can turn it off. SHARP WHERE IT MATTERS • Modern H.265 video keeps text crisp while using less data. • Quality adapts to your connection on its own: 720p when the network is tight, a sharper 1080p when it has room. RECOVERS BY ITSELF • Wi-Fi drops, cellular switches and server restarts are handled automatically: the stream reconnects without you touching the phone. • Designed and tested for long sessions without slowing down or running out of memory. SIMPLE BY DESIGN • One big button to start and stop. A timer shows how long you have been live. • Your Device ID is always on screen, so the right phone is easy to find. • Light and dark appearance. IN YOUR CONTROL • Auto quality is recommended, or set resolution, frame rate and bitrate yourself. • Export logs in one tap if you ever need support. HOW IT WORKS 1. Enter your Device ID in NMX Viewer. 2. Tap the button to start the broadcast. 3. Open nmxviewer.com and watch your iPhone live. NMX Viewer uses the iOS screen broadcast feature. iOS shows a red indicator while the broadcast is on, and you can stop it at any time from the app or Control Center.
