I built Airvia because I wanted my Android phone to play on my HomePod, and nothing free actually spoke real AirPlay 2.

Airvia captures your phone's audio output — Spotify, YouTube Music, podcasts, radio, almost any app — and streams it to your speakers:

• Real AirPlay 2 (transient HAP pairing, encrypted channels, buffered ALAC), confirmed playing on a real HomePod — plus AirPlay 1/RAOP fallback, DLNA/Sonos, and Chromecast
• Multi-speaker casting with a separate volume slider per speaker, and your phone's hardware volume buttons control the speaker while casting
• Per-app capture if you only want certain apps cast
• 5-band EQ + preamp, now-playing metadata with artwork, sleep timer
• Android 10+, no root, no account, no ads, no trial limits

Honest limits: apps can opt out of audio capture and DRM output is never captured, and AirPlay's buffer means a second or two of delay — great for music and podcasts, not for lip-syncing video.

It's free and open source (MIT). APK and source are on GitHub — feedback and bug reports welcome, especially from anyone with receivers I don't own.

Built by me, an independent developer — I designed it, decided every feature, and tested everything on my own devices. It’s built on top of open-source projects.
