Your music. Your server. Everywhere you go. Substreamer turns your Subsonic-compatible server into a personal streaming service. Browse, play, and download your entire music library on iPhone and iPad — free, with no ads, no subscriptions, and no data collection. Verified with Navidrome, Subsonic, Gonic, Nextcloud Music, and Ampache. Also compatible with Airsonic-Advanced, Funkwhale, Supysonic, and other Subsonic API servers. STREAM & DOWNLOAD Stream in full quality or choose a bitrate that suits your connection. Download albums and playlists for offline listening with background queue processing and automatic recovery. Substreamer switches to offline mode automatically when your server is unreachable. TUNED IN — SMART MIXES Personalised playlists powered by your listening history. Time-of-day mixes, deep cuts from similar artists, decade time machines, genre blends, favorites radio, and a custom mix builder — all generated from your own library, not an algorithm trained on someone else's taste. LISTENING ANALYTICS See your play history, top artists, albums, and songs, most active listening hours, activity heatmaps, and listening streaks. Scrobbles queue locally when you're offline and sync automatically when you reconnect. Exclude specific albums or artists so one-off plays don't skew your stats. LIBRARY MANAGEMENT Browse by album, artist, or playlist. List and grid views with alphabetical quick-scroll for large libraries. 5-star ratings and favorites sync with your server. Create and manage playlists, reorder tracks, or save your current queue as a new playlist. PLAYBACK Background playback with full lock screen and notification controls. Adjustable playback speed, shuffle, and repeat. Share albums or playlists with configurable links. BEAUTIFUL & PRIVATE Light, dark, and system themes with custom accent colors. Album art color extraction for immersive detail views. No tracking, no analytics, no account required — your music stays between you and your server. OPEN SOURCE Substreamer is open source under the GPL-3.0 license. Browse the code, report issues, or contribute at github.com/ghenry22/substreamer.
Again Music

Again Music is a free music player for the songs you already own. There is no feed, no banners, and no algorithm deciding what comes next. Just your music, and a player that finally feels like yours. YOURS, NOT THE ALGORITHM'S No recommendations. No "made for you" that was made for everyone. Your page is built only from what you actually do: the records you played, the artists you saved, and your playlists, albums, and songs. Tap the heart on a song and it stays. That is the whole system. THE CRATE Your recent listens stack up like a crate of records you can flip back through. Pull one out and it plays. It is the fastest way back to whatever you had on last night. MAKE IT YOURS Five title fonts, five app icons, and a true black dark mode. Set it up once and it feels like your own player, not someone else's. EVERY FEATURED ARTIST, ONE TAP Tap the credits on any song, pick a name, and land on that artist's page. Features, collabs, producers who sing, all one tap away. BRING YOUR MUSIC One tap imports your Apple Music library: your playlists and your recently added songs. Everything lives right where you expect it, ready the moment you open the app. WE COLLECT NOTHING Again Music has no ads, no accounts, no analytics, and no tracking. Everything you save lives on your phone. The App Store privacy label says "Data Not Collected" because there is genuinely nothing to collect. FAST, AND OUT OF THE WAY The whole app weighs less than a photo. It opens instantly, remembers exactly where you were, and never gets between you and the next song. ALSO IN THE BOX · A home screen widget that plays, pauses, and skips without opening the app · Full lock screen, AirPlay, and background playback · A queue you control: play next, add to queue, reorder on the fly · Search that learns which artists are yours · Session restore: close the app mid-song, come back tomorrow, it is still there EVERYTHING, FREE The whole app is free. No subscription to the app, no in-app purchases, no locked features. THE FINE PRINT Again Music requires an Apple Music subscription to play songs. If you are not a subscriber, the app offers to start Apple Music for you. It is an independent app and is not affiliated with Apple. Made by one person who wanted their music to feel like theirs again.
