A £15 Raspberry Pi Zero 2 W and a small USB DAC beat a £250 wireless speaker for kitchen audio when the software layer is right. That is the argument XDA made last week and it is one the DIY audio community has been running for a decade. The result is a wireless hub that receives streams, obeys voice control, and sounds better than anything Bluetooth ever managed. The best DIY Wi-Fi speaker control apps for Android are the tools that get music onto that hub and keep it in sync with the rest of the house.
We tested nine control apps against a mixed audio stack that included a Pi Zero 2 W in the kitchen, a Chromecast Audio holdout in the office, and an old set of powered monitors driven by a Raspberry Pi 4. The seven picks below cover the major protocols: UPnP, DLNA, Snapcast, Roon RAAT, Squeezelite, and Chromecast, plus the streaming service integrations that most people start from.
What to look for in a DIY audio control app
- Protocol coverage. UPnP, Chromecast, and Snapcast between them reach almost every DIY audio target.
- Gapless playback. Most DIY setups are album-listeners. Any control app that gaps between tracks is out.
- Multi-room grouping. The whole point is to move audio around the house without walking back to the source.
- Local library and streaming service parity. A single app that reads a Plex library, a Jellyfin library, and Spotify saves three home screens of apps.
- Zero telemetry mode. DIY audio users care about telemetry. Any app that phones home should have a toggle.
- Battery honest. A control app that keeps a foreground service running for zero benefit is a battery drain.

The apps
1. Spotify, best when the Pi runs Spotify Connect
Spotify on Android becomes a control app the moment the Pi runs librespot or a similar Spotify Connect endpoint. The phone picks the Pi from the device menu, streams start on the speakers, and playback survives locking the phone. The 2026 Spotify Connect version supports group speakers, so grouping the Pi with a Chromecast in the living room works from the same picker.
Where it falls short: playback quality caps at 320 kbps Ogg, and any dropout blames the network layer rather than the codec.
Pricing: free with ads. Premium around $12 per month for lossless and multi-device.
Platforms: Android, iOS, desktop, web.
Download: Aptoide · Google Play
Bottom line: the default controller for a librespot setup.
2. BubbleUPnP, best for bridging UPnP and Chromecast
BubbleUPnP by Bubblesoft is the veteran of Android UPnP control. It streams from a UPnP or DLNA server (Jellyfin, Kodi, or the Pi’s minidlna) to a UPnP renderer, but the real trick is the “Chromecast bridge” that translates a UPnP stream into a Chromecast-compatible session. That is what lets the kitchen Pi and the living-room Chromecast play the same stream in sync.
Where it falls short: the UI is dense and dated in places, and the paid unlock is required for the bridge.
Pricing: free tier limited. License one-time around $5.
Platforms: Android.
Download: Aptoide · Google Play
Bottom line: the app that stitches a UPnP library to a Chromecast household.
3. Snapcast Android, best for a multi-room Pi setup
Snapcast Android is the client and controller for Snapcast, the multi-room synchronisation server that most Pi audio guides now recommend. The phone joins the group, controls per-zone volume, and switches sources between MPD, Spotify, and AirPlay. Sync latency below 20 ms is the norm on a decent network, which is what “actually multi-room” means.
Where it falls short: setup requires a running Snapserver on Linux. This is not a plug-and-play app.
Pricing: fully free, open source.
Platforms: Android, iOS, web.
Download: Aptoide · Google Play · F-Droid
Bottom line: the correct answer for a Pi-first, whole-house audio build.
4. Roon Remote, best for bit-perfect streaming to a Pi
Roon Remote on Android controls a Roon Core running on a NAS or PC. The Pi becomes a Roon Bridge endpoint via HiFiBerry OS or Ropieee, and the phone drives what plays where. Roon’s metadata layer is still the best in the business for anyone with a real album collection, and RAAT keeps timing tight enough for house-wide sync.
Where it falls short: Roon Core is not free. The current subscription runs around $15 per month or lifetime around $830.
Pricing: Roon Remote is free with a Roon Core licence.
Platforms: Android, iOS, Windows, macOS.
Download: Aptoide · Google Play
Bottom line: the paid option that hi-fi households will not switch away from.
5. Squeezer, best for a Logitech Media Server holdout
Squeezer is the Android controller for Logitech Media Server, which is now open source under the “Lyrion Music Server” name. LMS on a Pi drives Squeezelite endpoints, which is another wildly popular DIY setup because it plays flac, dsd, and internet radio equally well. Squeezer controls playlists, groups, and per-endpoint volume.
Where it falls short: LMS installation is more manual than most competitors.
Pricing: fully free, open source.
Platforms: Android.
Download: Aptoide · Google Play · F-Droid
Bottom line: keep it for Logitech Media Server/LMS households.
6. Home Assistant Media, best for automation-driven playback
Home Assistant on Android becomes a media player when the underlying Home Assistant Core wires up media_player integrations for the Pi, the Chromecast, and any UPnP renderer. That means “bedtime playlist” fades out on schedule, “focus mode” mutes the kitchen, and “shower time” pumps a specific podcast to the Pi in the bathroom. The control surface fits inside the Companion app’s dashboard.
Where it falls short: setup is a project. The reward is a house that plays music on its own.
Pricing: free, MIT open source.
Platforms: Android, iOS, web.
Download: Aptoide · Google Play · F-Droid
Bottom line: the layer that turns audio into automation rather than manual playback.
7. Symfonium, best for a local library plus streaming services
Symfonium by Tomasz Litwiniuk reads a local Android library, a Subsonic-compatible server, a Jellyfin server, and streams to Chromecast or UPnP renderers. Its offline cache and gapless playback engine are among the best on Android, and the interface treats hi-fi listeners with respect: replay gain, exclusive DAC output, and lossless-preferred stream selection.
Where it falls short: paid. The reward is the least fussy Android audio app currently in active development.
Pricing: fully-featured trial. One-time around $10.
Platforms: Android.
Download: Aptoide · Google Play
Bottom line: the paid pick worth making for anyone who owns music files.
How to pick the right one
- Streaming service already lives on a Pi: Spotify or Roon Remote.
- The house is Chromecast-plus-UPnP: BubbleUPnP.
- A Pi hub controls three rooms: Snapcast Android.
- Logitech Media Server or Lyrion Music Server: Squeezer.
- Automation drives playback: Home Assistant Media.
- Local library plus a self-hosted server: Symfonium.
FAQ
What is the cheapest way to get whole-house audio on Android? Old powered speakers plus a Raspberry Pi Zero 2 W and a USB DAC per zone, controlled with Snapcast Android. The parts cost less than one wireless speaker.
Does Spotify Connect work with a Raspberry Pi?
Yes. Install librespot or Raspotify. Spotify on Android will see the Pi as a Connect endpoint on the local network.
Which Android app supports gapless multi-room audio? Snapcast Android for pure multi-room. Roon Remote for a paid, timing-sensitive setup.
Can I stream music from Android to a Chromecast Audio in 2026? Yes. Google discontinued the Chromecast Audio hardware but existing units still respond to Cast targets. BubbleUPnP and Home Assistant both list them.
Do these apps work offline? Symfonium, BubbleUPnP, and Roon Remote cache libraries for offline listening. Spotify and streaming services need service tiers that allow offline downloads.
