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.

I tried a lot of apps, including some that are still being developed, but this one was the only one that wor my rd consistently and could donate all the things. I wanted. Good wotk! ### 5/5 — Nect button not working *2026-07-23* Hi! I found a bug in the app. When I play music from the Songs tab, the Next button doesn’t work. It won’t skip to the next track, even though the song is playing normally. Could you please look into this issue? Thanks for all your hard work on the app. ### 3/5 — Falta PT-Br *2026-07-15* O app parece bom, mas falta suporte ao idioma PT-BR e também suporte a lyrics, pra acompanhar a letra da música, pra ele ficar 100% ### 5/5 — Great experience! *2026-07-06* I just recently got into self-hosting my collection and I needed an app to replace the other streaming apps I was paying way too much for. The interface is intuitive. The only feature I wish it had was a way to automatically download favorite songs or just make a playlist since you can download playlists. Maybe that would be harder since playlists are created and saved on the server-side? Still, this app was the first one I tried and I have been loving it! ### 5/5 — Super aplikacja *2026-07-04, version 8.0.73* Wszystko co potrzebujesz jest tu dostępne, po za Radio ### 5/5 — Really well designed ui *2026-06-28* This is probably the best designed ui for streaming your music media, I really how the layout is only thing would make it perfect is adding the option to move the order of the queue. **Developer response:** Thanks for the 5 stars! Really glad the UI is hitting the mark for you. Queue reordering is a great idea — it's something we've thought about but haven't built yet since it starts to add complexity to the interface. If this is important to you, the best way to get it on our radar is to open a request on GitHub: https://github.com/ghenry22/substreamer/issues. We love hearing ideas from our users and tracking them there helps us prioritise. Thanks again for the feedback! ### 5/5 — Amazing *2026-06-26, version 8.0.73* For an app thats free and allows to utilise self-hosted media solutions it's simply incredible. Amazing user interface, fuctionality and reliability. I cannot state how great it truly is! Serious props to the dev ### 5/5 — Die beste Musik App! *2026-06-24, version 8.0.73* Zuverlässig und es funktioniert alles! Vielen Dank für deine Mühen! ### 5/5 — Приложение становится только лучше *2026-06-23, version 8.0.73* С обновлением исправили создание волны по эпохам и это просто прекрасно. Не понятно почему треки, которые отмечены как «нравится», попадают в navidrome не в избранное. Это странно. ### 5/5 — Great player *2026-06-23* After recently setting up my Navidrome server, I wanted something clean with more options than just using the browser. Really glad I found this one. It works beautifully. Thank you to the dev. I owe you a cup of coffee **Developer response:** Thanks for the 5 stars! Really means a lot to hear that Navidrome + Substreamer is hitting the spot for you. And hey, about that cup of coffee — you're in luck!
