Relayo mirrors your iPhone to your TV — Chromecast, Google TV, and now Samsung, LG and other smart TVs. Nothing to install on the TV side. WORKS WITH Chromecast (all generations) · Google TV · Nvidia Shield · Google Nest Hub TVs with Chromecast built-in from Sony, TCL, Hisense, Vizio, Xiaomi, Philips, Panasonic, Sharp, Skyworth, Thomson and more. NEW: Samsung, LG and other smart TVs that support DLNA — including many Sony, Panasonic, Philips and Hisense models. Connect your iPhone and TV to the same Wi-Fi, open Relayo, and your TV shows up in the list. No extra box, no app on the TV. PLAY A FILE — BEST QUALITY Pick a video from your library or any file on your device and Relayo sends it straight to your TV untouched. No re-encoding, no quality loss. On Chromecast and Google TV, if the format isn't supported, Relayo converts it on the fly and starts playing within seconds. Full playback controls: play, pause, scrub, skip 10 seconds — from the app, from your Lock Screen, or from the Dynamic Island while you use other apps. MIRROR YOUR SCREEN Send your whole display to the TV — photos, presentations, browsing, anything. App audio comes along if you want it. Quality adapts to your network automatically. If Wi-Fi gets busy, Relayo lowers the bitrate instead of freezing. SHARE FROM ANY APP Send a video to your TV straight from the share sheet — Photos, Files, or anywhere else that offers sharing. BUILT TO STAY OUT OF THE WAY Two taps to start. Reconnects on its own if Wi-Fi drops or the TV restarts. A Live Activity keeps the session on your Lock Screen and Dynamic Island while you do something else. Available in 19 languages. No ads. No subscriptions. No account. PRIVATE BY DESIGN No servers. No analytics. Nothing is collected, stored or uploaded — there is nowhere for your data to go. Your screen and files travel directly from your iPhone to your TV over your local network. GOOD TO KNOW - Screen mirroring runs a few seconds behind — fine for photos and presentations, not for gaming or fast interaction. For films, cast the file instead: it plays in full quality with no delay - Mirroring stops when your iPhone locks; this is a system limitation - On Samsung, LG and other DLNA TVs, playback is controlled from inside the app, and which file formats play depends on the TV; MP4 videos and JPEG photos work on almost all of them - Protected content from streaming services can't be mirrored, due to system restrictions - MKV and AVI files aren't supported — convert to MP4 first - If your TV doesn't appear, it may use a casting system Relayo doesn't support yet Relayo is not affiliated with or endorsed by Google, Samsung, LG or any other TV manufacturer.
