SubSonify: Navidrome Player
Subsonic client with CarPlay
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New in 1.3 for Navidrome: gapless playback, For You mixes, and your queue survives a restart.
SubSonify is a native iOS client for self-hosted music servers: Navidrome, Airsonic, Ampache, gonic, LMS and anything else that speaks the Subsonic API. Your library, offline, in CarPlay, on Apple Watch, and one "Hey Siri" away. There is no tracking in it, and the only server the app talks to is yours. Free is the whole app at ten songs a day; Pro only removes the cap.
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. 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 download on their own.
• CarPlay. Browse, search and play from the car screen, with artwork, queue, Up Next, 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. "Hey Siri, play [artist] on SubSonify" plays from your server. Artists, albums, songs, playlists, or "play something" to shuffle the library. Shortcuts too.
• Song Radio. Start a radio from any song, and save the result as a playlist.
• Internet radio. If your server has stations configured, they show up. If not, the section stays hidden.
• Crossfade and quality. Adjustable crossfade, 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 keys, SubSonify logs in with a 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 go to your server and nowhere else.
WHAT IT COLLECTS
Nothing. There is no account to create, and the app ships without an analytics SDK or a crash reporter. Listening history, playlists, downloads and settings stay on your device and your server. The app makes two kinds of connections: to your server, and to Apple for purchases. The one exception is internet radio: stations stream straight from the broadcaster, who can see your IP address.
FREE AND PRO
Free means ten songs a day with every feature included: downloads, offline playback, CarPlay, the watch app, sync, search and playlists. Pro removes the cap and does nothing else. If ten songs a day is enough, the app costs nothing, ever.
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.
Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours of the end of that period. Manage your subscription and turn off auto-renew in your Apple Account settings after purchase.

Login over Tailscale works again. A server at a tailnet address such as 100.x.x.x, or at a .ts.net name with a port over plain http, connects like any other. The same applies to servers reached by DDNS name or any address outside your home network, and to Apple Watch.
Smooth playback on phones with little free space.
Changing songs in CarPlay shows the new song's progress from the start.
Library sync completes even when the server has removed an artist or album.
