Mirror your iPhone or Mac screen to Chromecast and Google TV, or play video files on the TV in full quality. iPhone's built-in Screen Mirroring only works with AirPlay, so Chromecast never shows up there — Relayo fills that gap. No ads, no subscription, no account, and nothing to install on the TV. Everything stays on your local network.

Partial Mirroring to Chromecast and Google TV is possible with the Google Cast SDK and iOS ReplayKit, but iPhone screen capture and streaming over the Cast protocol are constrained and fragile, requiring deeper platform-level work.
What it would actually take: An iOS app would capture the screen via ReplayKit's broadcast extension, encode H.264, and stream it to a Cast receiver using the Cast SDK, with a Mac client handling capture through ScreenCaptureKit. The hard parts are low-latency encoding, Apple's sandbox limits on extensions, and keeping up with undocumented or changing Cast behavior, which takes native media and networking expertise.
