Lagu for iPhone

A Plex music player
for iPhone.

Lagu for iPhone plays the music library on your Plex Media Server with lossless audio, radio drawn from your own collection, and downloads for when the signal goes. It is a SwiftUI app for iOS 26, with widgets, Siri, AirPlay, and CarPlay, and it doubles as the remote for Lagu on your computer or TV.

Lagu’s Home tab on iPhone: a Good evening greeting reading Make it an occasion, Celebratory Radio and Shuffle Library buttons, a Recently Played row, the start of Made for You, and the mini-player and tab bar along the bottom.
Now Playing on iPhone for Invisible by Duran Duran: the Future Past cover, a four-star rating, a FLAC 16-bit / 44.1 kHz label, the seek bar, transport controls, and a volume slider, with the screen tinted red and green from the cover.
The album page for Tame Impala’s Currents on iPhone: the cover, 2015 · 13 songs · 51 min, a FLAC 24-bit / 44.1 kHz label, Play and Shuffle buttons, and the start of the track list.

01 · On the iPhone

Wired into
iOS.

Sign in through Plex’s own page, pick a server, and the library loads. Your Plex password never passes through Lagu.

Three widgets

Now Playing, with working controls, on the Home Screen or lock screen. Quick Play, with three or six of your recent albums and playlists. This Week, with your plays, top artist, and top song.

Siri

Ask for a song, album, playlist, genre radio, or your loved tracks by name. “Like this song on Lagu” and “What’s playing on Lagu” work too.

Shortcuts

Play, pause, skip, and like are ready-made phrases, with no setup. The Play action takes a search, so a shortcut can start any album.

Lock screen and AirPlay

Full controls with the artwork, and a star on the lock screen that gives the playing song five stars in Plex. AirPlay sends playback to speakers and TVs from Now Playing.

Quality for each connection

One streaming quality on Wi-Fi and another on cellular, from Original down to 128 kbps, with the bitrate on Now Playing whenever Lagu is converting.

CarPlay

Home, Library, Search, and Downloads on the car’s screen, with your playlists and artists in Library. When the signal drops, CarPlay switches to your downloaded music.

iPhone Duo, open or folded

Unfolded, Lagu takes the iPad layout, with the sidebar and the player bar in landscape, and turns with the phone. Folded, the cover screen keeps the iPhone layout.

02 · The player

Sound and
the library.

Lagu takes its color from the album that is playing, in Bloom or the flat Mono look, dark, light, or following the phone. Mono comes in a Primary colour you pick, true-black OLED included.

Lossless, gapless, leveled

FLAC direct-plays from your server with the format named on Now Playing, and album tracks run into each other without a gap. Every track plays at about the same loudness: one your server hasn’t analyzed is measured on the phone.

Ten-band EQ

A preamp, twelve presets, presets of your own, and AutoEq profiles for about 2,900 headphones, running in Lagu’s audio engine on the phone.

Downloads

Albums, playlists, artists, and songs, at Original quality or 320 down to 128 kbps. Wi-Fi only by default, and kept-synced playlists follow edits on the server.

A queue that stays

Force quit or restart the phone, and the queue comes back paused where you left it. A Play from AirPods, the car, or the lock screen picks it up; opening Lagu plays nothing by itself.

Seven visualizers

Spectrum, Radial, Tide, Orbit, Cover Flow, Oscilloscope, and Trackprint, in the colors of the album that is playing.

Every library as one

All the music libraries on your server, browsed together in one list. Switch off any you do not want in Settings.

Lyrics, offline too

Synced lyrics follow the song, and a download keeps its lyrics, so they show in airplane mode. Long-press a line to copy up to six, or share them as a card with the cover.

Select many

Pick songs on an album, a playlist, or Songs, or Select All, then Play Next, Add to Queue, Add to Playlist, or Download them together.

Swipe to queue

Swipe a song right to Play Next or left to Add to Queue, as in Apple Music. A full swipe does it at once.

Artist pages

A full-width artist photo, ten popular songs, your own plays and most played albums, then About and Similar artists. With Plex Pass on the server, Sounds like too.

LAGU REMOTE

The phone runs Lagu on your other screens.

Pair the iPhone with Lagu on a Mac, Windows or Linux PC, Apple TV, or Android TV by scanning a QR code. From the phone you can browse, search, queue, seek, and use the volume buttons for Lagu’s volume on the computer, over your own Wi-Fi, or through Lagu Relay when you’re away from home. If both sides have a queue, Lagu asks which one to keep, and Move playback here brings the music back to the phone. The lock screen, Control Center, and your headphone buttons drive the computer too.

Lagu on an iPhone with the Choose where to play sheet open: the Windows PC DESKTOP-OVP4628 is ticked and shows the track it is playing, with a Linux desktop and a Google TV streaming box below it, each listing its certificate fingerprint.

What it doesn’t do

The gaps,
listed.

What the iPhone app does not do yet. The platform table has every feature, cell by cell.

No DLNA speakers

Network speakers like WiiM are on Android and desktop. On iPhone, AirPlay covers speakers and TVs.

A remote, not a host

The iPhone controls other screens. Another device cannot control Lagu on the iPhone.

CarPlay search needs iOS 27

On iOS 26 the CarPlay Search tab shows recent results, because Apple’s search template for audio apps arrives in iOS 27.

Portrait, apart from Now Playing

The app stays upright. Now Playing turns with the phone, and an unfolded iPhone Duo turns freely.

Getting it

From download
to music playing.

Join on TestFlight

iPhone, iPad, and Apple TV share one TestFlight listing, and the Apple Watch app comes with the iPhone one.

Questions

Asked about
this platform.

Is there a Plex music player for iPhone?

Yes. Lagu is a music player for Plex with a SwiftUI iPhone app. It plays your Plex library lossless and gapless, has a ten-band EQ, downloads for offline listening, widgets, Siri and Shortcuts, AirPlay, and CarPlay.

Can I ask Siri to play my Plex music?

Yes. Ask Siri for a song, album, or playlist by name and it plays in Lagu, smart playlists included. Saying “on Lagu” makes it certain; iOS has no default-music-app setting, so a bare request depends on what Siri has learned.

Does Lagu for iPhone work offline?

Yes. Download albums, playlists, artists, or songs, and they play with no connection, lyrics included. Search works across your downloads offline too.

Does Lagu for iPhone need Plex Pass?

No. Playback, downloads, the EQ, playlists, and Lagu Remote work without it. Sonic radio, moods, and Plex-fetched lyrics rely on Plex Pass on the server. Streaming away from home takes a Plex Pass on the server owner’s account or a Remote Watch Pass on yours.

What does Lagu for iPhone cost?

It is free during the beta. At launch, one $1.99 App Store purchase covers iPhone, iPad, and Apple TV together, and Family Sharing works. There is no subscription.
