What it does
Cast a video file
Pick a video, song or photo and it plays on your TV untouched — no re-encoding, no quality loss. Unsupported formats are converted while playing.
Mirror your screen
Put your whole iPhone or Mac display on the TV: presentations, photos, browsing. Sound comes along, and quality adapts to your Wi‑Fi on its own.
Nothing to set up

Guides

No account. No servers. No analytics in the app. Your screen and files travel directly from your iPhone or Mac to your TV over your own network.
Questions
Can I mirror my iPhone to a Chromecast?
Yes. iPhone can't mirror to Chromecast on its own, because AirPlay only works with Apple TV and AirPlay-compatible TVs. Relayo adds that missing link: open the app, pick your Chromecast or Google TV and start mirroring. Nothing needs to be installed on the TV.
Can I mirror my Mac to Google TV?
Yes. Relayo lives in your Mac's menu bar. Pick your TV, choose Mirror screen, and your display appears on the TV within a few seconds.
Does it work with Samsung or LG TVs?
Yes, on iPhone. Relayo finds Samsung, LG and other smart TVs that support DLNA on your Wi-Fi, so you can mirror your screen or send videos and photos to them with nothing to install on the TV. On Mac, Relayo works with Chromecast and Google TV.
Is there a delay?
Screen mirroring runs a few seconds behind, which is fine for video, photos and presentations but not for gaming. For films, send the video file instead: it plays in full quality with no visible delay.
