What's new · All changes · Watch the film

1. Download Prism.apk on your phone (Android 8.0 or newer).
2. Open it. Android will ask you to allow installs from your browser or file manager.
3. That's it. You can sign in with your YouTube Music account to sync your library, or skip that.

Updates: when there's a new version, tap the banner on Home. Your downloads, history and settings are kept.

On a TV (Android TV or Google TV): type code 8986606 into the Downloader app on the TV. Or, on your phone, turn on Settings → Speakers, TVs & browser → Share Prism with a TV, then type the address it shows into the TV.

The optional lock screen player needs a permission called "Display over other apps". From Android 13, Android may refuse it at first, because Prism doesn't come from a store. To allow it:

1. Open Prism's App info page, and tap ⋮ at the top right.
2. Tap Allow restricted settings.
3. Go back and allow the permission.

Prism walks you through this on the setting's page. It uses the permission only to bring its player up on your lock screen, and never draws over other apps.

Fixes, and lighter on your battery.

• Less work in the background. Prism now slows or stops its song scans when you've left it, and they create far less work for your phone's memory.
• The player opens more smoothly, with its cover ready before it slides up.
• Quick picks come sooner, and pulling down really gives you new songs.
• Search in Library, and a scrollbar you can hold on long lists.
• New folder in Library, and an easier-to-read album description.
• Your photo background is back if your phone is in German, Italian, Russian, Polish, Swedish, Hungarian, Malay or Filipino.

See every change in the changelog.

		Lyrics, word by word Lyrics from ten sources, with translations and pronunciation for languages like Korean, Japanese and Arabic. Pick from six styles, or turn the cover and lyrics into a full-screen lyric video.
		Sing and DJ mode Sing takes the singer's voice out of the song, so you can sing along to the real track. DJ mode puts your queue in an order where each song blends into the next.
		Mixes made on your phone Daily Mixes, new music from your artists, and a radio that keeps playing when your queue ends. Your listening history never leaves your phone.
		Replay and Rewind See your top songs, artists and genres for any time you pick. Every December, you get a Rewind story of your year to share.
		Find songs, and podcasts too Find out what song is playing around you. Listen to podcasts with speed control, skip buttons, and a memory of where you stopped.
		No account needed Make playlists and save albums without signing in. Or sign in to sync your likes, playlists, albums and artists with YouTube Music.

Big lyrics, music videos and Sing, with screens made for a remote. Your phone can act as the remote too, and sign the TV in for you.

There is no Prism server and no tracking. Your history, recommendations, downloads and settings stay on your phone. If you sign in, your session is stored only inside the app.

Prism connects directly from your phone to YouTube Music, to lyric services, and to a few music services for genres and release dates. A few features also send what they need to work:

• Song recognition sends an audio fingerprint to Shazam, never the sound itself.
• Lyrics translation and some pronunciation guides send the lyrics' text to Google Translate.
• Extras you turn on, such as Last.fm, Spotify, Discord, Wikipedia bios and RSS podcasts, talk to those services.

Listen Together, Blend and moving playback to another phone only talk to other devices on your Wi-Fi, and only while they're open.

Prism is free, and I build it in my spare time. If you enjoy it, you can buy me a coffee on Ko-fi. Every tip helps, and none is expected.

Prism doesn't copy artwork, fonts or code from other apps, but many of its ideas and sources come from elsewhere.

Ideas

• Apple Music: artist pages, starred album tracks, artist name styles, animated covers and Sing's controls. BitChord, itself modeled on Apple Music, inspired the player.
• Spotify: Daily Mixes, Release Radar, Smart Shuffle, Blend, Crossfade, DJ-style mixing, share cards, and Listen Together (from Spotify Jam). Spotify Wrapped inspired Replay and Rewind.
• Spotify Connect and Apple's Handoff: playing on and moving music between devices. Open-source projects such as pychromecast and node-castv2 document how Google Cast works.

Sources and code

• Music and song info: YouTube Music. Genres from Apple's iTunes Search API and Deezer. Release dates from Deezer.
• Lyrics: Better Lyrics, NetEase, KuGou, LyricsPlus, Bini, LRCLIB, Unison, Genius and YouTube Music. Lyrics belong to their rights holders.
• Animated covers: Apple Music, Tidal and the ViVi Music canvas list.
• Playlist import: handed off to TuneMyMusic, a separate service. Prism shares nothing with it.
• Signed-in playback: yt-dlp's EJS solver (Unlicense), with meriyah and astring.
• Song recognition: Shazam's service, with the fingerprint code ported from SongRec (GPL-3.0).
• Sing: Deezer's Spleeter model (MIT), converted by sherpa-onnx, on ONNX Runtime.
• Headphone correction: AutoEq (MIT).
• Fonts: Outfit, Manrope, Plus Jakarta Sans, Urbanist, Nunito, Fraunces, Geist Mono, Atkinson Hyperlegible Next and OpenDyslexic, all under the SIL Open Font License.
• Libraries: NewPipe Extractor, Haze, Coil, Media3 ExoPlayer and more. The app lists them all with their licenses in Settings → Backup & about → Open-source licenses.
• The film's music: "Minimal Tech" by PaulYudin (Pixabay).
