About this app

Your Spotify + YouTube Music library, on your phone, in FLAC.

Stash mirrors your Spotify and YouTube Music libraries to your Android phone. You connect each service, pick the playlists and mixes you want, and Stash either downloads them as real FLAC files for offline playback or surfaces them as a streaming index so you can stream tracks without filling up your storage. Same library, two modes, one tap to switch.

There's no Stash account. No subscription. No ads. No analytics. Your credentials live on your phone, encrypted, and the only network traffic Stash makes is to Spotify and YouTube themselves.

Home screen — Daily Mixes, sync stats, supporter pill Now Playing — FLAC 24/44 lossless

Online vs Offline Stash has two modes. They decide what a sync actually does.

Offline mode Sync downloads each track as a FLAC file (or the closest lossless source available) and stores it on your phone. Once a track is on disk you can play it forever with no connection. It costs storage but no recurring data.

Online mode is for people who don't want the storage hit. Builds a streamable local index of your library — Almost no storage, but you need a connection to play.

The FLAC backbone - QBDLX — a program that downloads streams directly from Qobuz. - arcod These are run by people doing it for the love of it — mostly solo, mostly free. They're the whole reason Stash can hand you a real lossless file instead of a re-encode. If Stash earns a spot on your phone, send a little of that their way: a thank-you, a tip, whatever you've got. We stand on their shoulders. 🙏

Library - Spotify + YouTube Music in one unified library — liked songs, playlists, daily mixes, every Spotify mix worth syncing - Bulletproof matching — finds the right version of a track 99% of the time - Last.fm scrobbling, optional, off by default - Wrong-match flag — if Stash picked the wrong version, tap once from Now Playing and it queues a re-search - Likes and History mirroring — When enabled, each track you like & stream in Stash lands in your Spotify & YouTube accounts.

Playback - 5-band equalizer with presets, bass boost, virtualizer - Crossfader - Normalizer - Synced lyrics, pulled from LRCLIB and scrolled with the track

Privacy - No Stash servers. No accounts. No analytics. No third-party crash reporters. - Cookies stored on-device, encrypted with AES-256-GCM via Google's Tink - The only network requests Stash makes are to Spotify and YouTube directly - GPL-3.0, every line of code is open source

What's new

v0.9.120Oct 25, 2026

Turn the album over: Now Playing now shows the back cover and the pages inside the album.
What's new - Flip the cover. Tap the album art on Now Playing to turn it over to the album's real back cover. While it's turned, swipe left or right to page through the inside: the booklet, the gatefold and the inner sleeve. Tap again to turn it back. Swiping to skip and double-tapping to seek work as before on the front. - Look up close. Pinch the cover, the back or any page and it lifts off the art to fill the screen. Pinch and drag to read the small print, then tap or press back to put it down. - Cycle album art. While Now Playing is open, the art slowly fades from the front to the back and through the inside pages, then round again. Touch the art to stay on a page. It's on for everyone; turn it off in Settings → Appearance → Cycle album art. - Albums for every song. Songs from Last.fm playlists and mixes often came in with no album, so they had no album page and no back cover. Stash now asks Last.fm which album each one is on, and fills in only the ones that were blank. - Your whole listening history, for the web. Settings → Library & Storage → Stash on the web can now include every play on this phone in the saved file, for Your record in the web player.
UX polish - The art for the next song is looked up while the current one plays, so the flip is usually ready the moment it starts. - Back covers and inside pages come from the Cover Art Archive, and from Discogs for albums the archive doesn't have. Pages from Discogs say "Data provided by Discogs" and link to the album there. - Deluxe editions, anniversary reissues and remasters find the original album's art.
Known limitations - Albums from smaller artists often have no back cover yet: nobody has scanned one into the Cover Art Archive or Discogs. - Discogs doesn't say which photo is the back, so Stash picks the likeliest one. Now and then the "back" is a gatefold's inside.
