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.

Verdict
The clearest difference is rating: Sonic Stream at 4.7 against SubStreamer's 4.0. Sonic Stream also leads on update cadence (every 5 days vs every 2 weeks). SubStreamer's advantage is ratings volume (145 vs 6). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Sonic Stream holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: SubStreamer has 145 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 72% of SubStreamer's written reviews are positive against 67% of Sonic Stream's, so the app with the better star average is not the one people write more warmly about.
SubStreamer ships an update every 2 weeks, Sonic Stream every 5 days. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
