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

v0.9.106Sep 17, 2026

If you connected Spotify, synced, and found your playlists empty, this update is for you.
Your playlists have their songs again After connecting Spotify and syncing, your playlists and Liked Songs showed a song count but nothing inside, and Home stayed empty. Both are fixed. - You don't need to reinstall. Run one sync after updating and the playlists you already have fill in. - Thanks to everyone who reported it.
Mixes can download now - In the Sync tab, every mix now has the same switch your playlists have. Switch a mix on and, in Download mode, it downloads — the same as any playlist. - Nothing downloads that you didn't switch on. Mixes start switched off. - Keep in mind: mixes change over time, so a switched-on mix will download its new songs as they arrive. - Home shows what you synced - In Online mode, your mixes, radios and playlists now appear on Home and in Library as soon as they've synced. You don't have to turn anything on first. - The "Personalize your Home" card only shows when there's nothing else to show.
Now Playing - Long song titles scroll across instead of being cut off with "…". - The extra FLAC badge next to the title is gone. The quality line underneath already tells you.
Good to know - Daily Discover builds itself over a few refreshes, so it can be empty for a little while on a fresh install. Playing music makes it better.
