Your libraries in one place
Klangraum connects approved audio libraries without uploading them to someone else's cloud catalogue. Server, account, and source remain visible while search and the playback queue work across them.
Self-hosted audio on iPhone
Your self-hosted music, native on iPhone.
A native iPhone app for self-hosted music on Plex, Jellyfin, Audiobookshelf, and OpenSubsonic-compatible servers.
What Klangraum does
Klangraum is being prepared for its first App Store release. There is no download link yet.
Built for music and long-form audio
Albums, artists, tracks, playlists, audiobooks, and audio dramas use library and resume behavior suited to their content. Movie, TV, and photo libraries are not imported.
Direct playback and offline listening
The app prefers Direct Play and can request a compatible alternative from the server when needed. Selected tracks can be validated, stored on the iPhone, and played without unnecessary server requests.
Local music stays local
You can import audio files with the iOS document picker or, after granting permission, include locally playable items from Apple Music Library. Klangraum does not upload this content to your music servers.
No tracking account
Klangraum operates no separate user account, contains no advertising, and uses no tracking or analytics SDK. Credentials are protected in the iOS Keychain.
