Relayo mirrors your iPhone to Chromecast and Google TV devices — nothing to install on the TV side. WORKS WITH Chromecast (all generations) · Google TV · Nvidia Shield · Google Nest Hub TVs and streaming devices with Chromecast built-in, including Sony, TCL, Hisense, Xiaomi, Philips, Panasonic, Sharp, Toshiba, Skyworth, Thomson and others. If your TV or streaming box mentions "Chromecast built-in", Relayo will find it. TVs that use other casting systems are not supported. 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. If the format isn't supported by your TV, 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 - Files are sent in full quality when your TV supports the format; anything else is converted to 1080p automatically - Protected content from streaming services can't be mirrored, due to system restrictions - MKV and AVI files aren't supported — convert to MP4 first Relayo is not affiliated with or endorsed by Google.

Verdict
The clearest difference is in-app purchases: Relayo at none against CountAI's 1. CountAI's advantage is iOS requirement (15.6 vs 17.6). On price, ads and device support there is nothing between them.
