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 Plex.
Plex client for iOS
Plex on iPhone, made for the road
RoadSonic turns your Plex 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.
Plex Media Server hosts your music alongside films and series. RoadSonic signs in through the official plex.tv PIN flow, discovers your servers and tries local, remote and Relay routes in that order — with no Plex Pass required for RoadSonic's own features.
Plex support is built on the official API and covered by protocol contract tests; a validation campaign on real Plex servers is still in progress. If something looks off with your server version, write to us: we add a test and tell you when it is fixed.
Connect Plex to RoadSonic
Add a source
Open Settings › Sources › Add a source and choose Plex.
Connect your Plex account
Tap “Connect my Plex account”. Sign-in happens on plex.tv with a PIN; RoadSonic never sees your Plex password.
Pick your server
Your servers are discovered automatically. Local, remote and Relay routes are tried in that order.
Let it sync
The music libraries of the server are indexed on the iPhone. The 7-day trial starts now, and the “Ready for the road” badge appears once the reserve is complete.
What you get with Plex in RoadSonic
CarPlay
Listen, Artists, Albums and Find on the car screen with artwork and Now Playing. Your Plex library, without menus to dig through.
Instant offline search
Your whole Plex catalog is indexed on the device. Two letters and results appear — even offline, even if the server is slow or far away.
Offline albums
Download any album for a trip. Downloads are visible, resume after a lost connection, are verified and never silently deleted.
Radio and smart playlists
An endless queue from your favorites, your play counts and community popularity. Daily Mix, Rediscover, Never played, computed on the device.
Lyrics, EQ and Siri
Synchronized lyrics and karaoke, 10-band equalizer with per-output profiles, gapless and crossfade, full voice control.
