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 Local files.
Local files client for iOS
Local files on iPhone, made for the road
RoadSonic turns your Local files 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.
No server at all? Import folders from the Files app — iCloud Drive, a NAS share, a USB drive — and RoadSonic plays FLAC, ALAC, MP3, AAC and every format iOS decodes, with the same search, Radio, lyrics, equalizer and CarPlay as a server library.
Connect Local files to RoadSonic
Add a source
Open Settings › Sources › Add a source and choose Local Files.
Pick folders
Select one or more folders from the Files app — iCloud Drive, a NAS share, a USB drive or another app's storage.
Files are copied
Files are copied into RoadSonic's managed storage so they stay playable with the screen off and inside CarPlay. The app's own Music folder in Files is always synced.
Enjoy
Local tracks appear next to your server libraries, with the same search, Radio, lyrics and equalizer.
