Ready for the road
20, 30 or 60 minutes of verified complete tracks always on the iPhone, refilled while you listen. Tunnels and dead zones never cut the music from gonic.
gonic client for iOS
gonic on iPhone, made for the road
RoadSonic turns your gonic library into a music player that keeps playing in the car. Connect in a minute, let the iPhone index everything, and drive with a verified reserve of complete tracks.
gonic is a minimal, fast Subsonic server written in Go, popular on Raspberry Pi and small NAS boxes. It supports transcoding profiles per client, so you can stream FLAC at home and Opus on cellular — RoadSonic caches whichever rendition the server sends.
Connect gonic to RoadSonic
Add a source
Open Settings › Sources › Add a source and choose OpenSubsonic / Subsonic.
Enter the address
Type the full server address including the scheme, for example https://music.example.com. Do not put the username or password inside the address.
Sign in
Enter your username and password. RoadSonic uses the Subsonic salted-token scheme, so your password is never transmitted.
Let it sync
The first sync indexes artists, albums and tracks on the iPhone. The 7-day trial starts now, and the “Ready for the road” badge appears once the reserve is complete.
