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

v0.9.105Sep 11, 2026

Your friends on Discord can now see what you're listening to in Stash. This update also lets you arrange your downloads the way you like, helps a restored backup bring your music back, and makes album covers sharper.
Show what you're playing on Discord Go to Settings → Accounts & Sync → Discord and sign in. While a song plays, your Discord status shows the song, the artist and the album cover. Pause, and it goes away. Discord doesn't officially support this for phone apps, so there's a small risk to your Discord account. Stash explains it before you connect, and you can disconnect any time. - Arrange your downloads your way Choose how your downloaded songs are sorted into folders: by artist and album, all in one folder, or one folder per playlist. Find it in Settings → Library & Storage → Folder structure. Stash can also move the songs you already have into the new arrangement. - Backups that bring your music back When you export a backup, you can now choose what goes in it, like just your liked songs. - Restored a backup on a new phone? Stash can download your songs again from Settings → Library & Storage → Library Health. - Account logins don't carry over in a backup, so sign in again after restoring. - Songs Last.fm thinks you'll like Connect Last.fm in Settings → Accounts & Sync, and Stash builds a playlist of recommendations for you. You'll find it in Library → Mixes.
Also new - Albums you've saved in YouTube Music now sync to Stash - Album covers look sharper. - Artist pages open faster. - The wrench button on Home now lets you report a problem or help translate Stash.
Good to know - After you move your songs into a new folder arrangement, the old empty folders stay behind. It's safe to delete them. If your music is on an SD card, moving it into a new arrangement hasn't been tried on a real phone yet. If you try it, let us know how it goes. - Connecting Last.fm takes two steps. If it doesn't work, start again and finish both steps right away.
