Volume.

Your audiobooks. Your server. Played beautifully. Volume is an expressive, privacy-first audiobook player built for people who host their own libraries. Whether your books live on Audiobookshelf, Jellyfin or Plex, Volume brings them together into one fluid, customisable listening experience, built natively for iOS in SwiftUI. WHY VOLUME Audiobooks are not long albums. They have chapters, you lose your place in them, and you return to them over weeks. Most players treat them like music. Volume doesn't. I built it for my own library first, as an indie project, and it connects straight to your server with nothing in between. MULTI-SERVER AND MULTI-ACCOUNT Connect to Audiobookshelf, Jellyfin or Plex. Switch between libraries and servers without losing your place. CHAPTER-FIRST PLAYBACK Per-chapter progress and time remaining, so you always know how far you are from a sensible place to stop. Full M4B chapter support, including parsing chapters Jellyfin doesn't expose through its API. UNDO LAST SKIP Clipped the next-chapter button in your pocket? Volume remembers your previous position and puts you back with one tap. CARPLAY AND AIRPLAY Browse your library, control playback and move between chapters safely from the car. Send audio to a HomePod, Apple TV or any AirPlay speaker straight from the player's route picker. ICLOUD SYNC Your library stays in step across every Apple device you own. OFFLINE LISTENING Download books to your device for flights, commutes and anywhere off-grid, with full download and progress management. ADVANCED PLAYBACK Variable speed to 3x, customisable skip durations, and a smart sleep timer with duration, end-of-chapter and fade-out modes. BOOKMARKS AND NOTES Save the moments that matter with timestamped bookmarks, attach notes to exact playback positions, and export everything to CSV, Markdown or YAML. A playback timeline keeps a record of how you actually listen. EXPRESSIVE, CUSTOMISABLE DESIGN Dynamic theming repaints the app around the cover art of whatever you're reading. Reorder your home screen sections, configure player button layouts, filter by genre, and enjoy a serif-led typographic design built for iOS. METADATA ENRICHMENT Integrates with Open Library for cover artwork, author information and descriptions, falling back to embedded file metadata. PRIVACY AND FREEDOM Volume is strictly client-side. Your server credentials, library data and playback statistics stay yours. No accounts, no ads, no third-party analytics, no tracking. Listen to your audiobooks, expressively.
