Arpeggi is an Open Subsonic client designed with the same clean aesthetic as Apple’s apps, built for people who care about how their app feels. Whether you're at home, in the car, or completely offline, your library is always within reach, beautifully presented and ready to play. Gapless playback across AAC, FLAC, ALAC, and OPUS keeps your albums flowing exactly as they were meant to be heard. ReplayGain support ensures consistent volume across your entire collection, and server-side transcoding lets you balance quality and bandwidth. Connect to multiple Subsonic servers and music folders from a single app. Arpeggi's continuous queue system keeps the music going, while Song and Artist Station modes let you explore your collection in a whole new direction. Download your favourite albums and playlists in the background — multiple files at once — so your music is ready before you go offline. Scrobbles are cached locally with timestamps and synced when you're back online, so not a single play goes unrecorded. Create and edit playlists directly from the app. Full CarPlay support keeps your eyes on the road. A customisable design means the experience adapts to you, not the other way around. Built entirely in SwiftUI with a native-first approach, every interaction in Arpeggi feels at home on iOS — fast, fluid, and familiar. Requires a Subsonic or Open Subsonic compatible server.
