Ready for the road
A verified reserve of 20, 30 or 60 minutes of complete tracks always sits on your iPhone. The next tracks download while you listen; tunnels and dead zones never cut the music.

Everything RoadSonic can do
RoadSonic is a music client for people who host their own library. Every feature below is designed for one situation: music that keeps playing, in the car, whatever the network does.
CarPlay done right
Listen, Artists, Albums and Find on the car screen, with artwork and Now Playing. Large targets, no nested menus, playback resumes where you left it.
One library, all your servers
Navidrome, Ampache, gonic, LMS, Airsonic, Nextcloud Music, Plex, Jellyfin, Emby and local folders merged into one catalog. Duplicates are matched by MusicBrainz and ISRC identifiers.
Search that never waits
Your whole library is indexed on the device. Two letters and results appear instantly — artists, albums, tracks — even offline, even on a slow server.
Radio, Artist and Album
An endless queue from your favorites, your play counts and community popularity, without repeating what you heard in the last three days. Say “Not for me” or “More like this”.
Lyrics and karaoke
Synchronized lyrics from your server or LRCLIB, with a karaoke view that follows the song line by line.
Sound you control
10-band equalizer with presets, loudness normalization per track or album, gapless playback and crossfade, with a separate profile recalled for speaker, headphones, Bluetooth, CarPlay and AirPlay.
Siri and Shortcuts
“Play Depeche Mode”, “Play my favorites”, “Start the radio”, “Like this track”: full voice control plus Shortcuts actions for albums, artists, playlists and downloads.

Your music server on CarPlay
RoadSonic was designed for the car first. The CarPlay interface shows exactly what you need while driving — and keeps playing through tunnels thanks to a verified reserve of complete tracks on the iPhone.
→Offline, verified, never silent
Streaming from your own server is great until the network drops. RoadSonic treats offline as the normal case: a pinned reserve, resumable album downloads and an on-device index that never needs the server to answer.
→Synchronized lyrics and karaoke
RoadSonic shows the words of what you are playing, synchronized with the music, and turns any track into a karaoke session — from your own files, not from a streaming catalog.
→Sound you control, per output
The same album should not sound the same on the car speakers and on in-ear headphones. RoadSonic keeps a separate sound profile for every output and recalls it automatically.
→From your server to the car in minutes
Connect
Enter your server address and credentials — or sign in with Plex PIN or Jellyfin Quick Connect. Passwords stay in the iOS Keychain and are never sent in the clear.
Sync and search
RoadSonic indexes your whole library on the device. Search, browse by letter, sort by year and build smart playlists — offline, instantly.
Drive
Start an album, an artist or the Radio. The “Ready for the road” badge tells you the offline reserve is complete before you leave.
