Stash App Offers Free, Open-Source Music Library Management
Stash, a new open-source application, allows users to manage their Spotify and YouTube Music libraries on Android devices. The app offers two modes: offline, which downloads tracks as FLAC files, and online, which streams music without taking up storage space. Stash does not require a subscription or account, and it encrypts user credentials on the device. The app bypasses official APIs by using login cookies, enabling features not typically available in third-party apps. Stash is distributed outside the Google Play Store due to policy restrictions on unauthorized downloads.
