SubSonify
Navidrome & Subsonic client
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
SubSonify is a native iOS client for Navidrome, Airsonic, Ampache, gonic, and anything else that speaks the Subsonic API. You run the server; this app puts your library on the phone, in the car, and on your wrist.
No accounts, no analytics, no tracking. The app talks to exactly one server: yours.
WHAT IT DOES
• Full offline library. The app keeps a local copy of your library, so browsing and search are instant and work with no signal at all. It syncs in the background; there is no "offline mode" to switch on.
• Downloads. Keep albums, playlists or single songs on the device. They survive reboots and keep playing when your server is down.
• Auto-download. Point it at your starred songs or any playlist and new additions get downloaded on their own.
• CarPlay. Browse, search and play from the car screen, with artwork, queue, shuffle and repeat.
• Apple Watch. Standalone playback: stream over Wi-Fi or LTE, or sync tracks to the watch and leave the phone at home.
• Siri and Shortcuts. Ask for an album, artist or playlist without unlocking the phone, or wire playback into your own Shortcuts.
• Internet radio. If your server has stations configured, they show up. If not, the section stays hidden.
• Crossfade and quality. Adjustable crossfade between tracks, plus separate stream quality for Wi-Fi and cellular: FLAC at home, transcoded on mobile data.
SERVERS AND LOGIN
Tested against Navidrome, LMS, Ampache and gonic. On servers with OpenSubsonic API key support, SubSonify logs in with an API key, so your password is never stored on the device. Everywhere else it uses the salted-token authentication every Subsonic server has supported for years. Credentials live in the iOS Keychain and are sent to your server and nowhere else.
WHAT IT COLLECTS
Nothing. There is no account to create, no analytics SDK, no crash reporter phoning home. Your listening history, playlists, downloads and settings stay on your device and on your own server. The app makes exactly two kinds of connections: to your server, and to Apple for purchases.
PRO
Pro is available monthly, yearly, or as a one-time lifetime purchase. The yearly plan starts with a free week. Prices are shown in the app in your local currency.
