ShelfDrop is an offline-first audiobook player for people who keep their own DRM-free audiobook files. Import audiobooks from the Files app, or start Receive mode and upload from a computer browser on the same Wi-Fi network. ShelfDrop copies your books into local app storage so you can listen without running a media server, cloud account, or manual media syncing. Features: - Import DRM-free .m4b, .m4a, .mp3, .aac, .wav, .flac, and .zip files. - Upload from a PC browser using local Wi-Fi Receive mode. - Import audiobook folders and multi-track books. - Play offline after import. - Save playback progress automatically. - Resume where you left off. - Adjust playback speed. - Use configurable jump buttons. - Use a sleep timer. - Show cover art when available. - Delete imported books and their local files from the app. ShelfDrop does not include, sell, or provide audiobook content. It is designed for audiobooks you already own and have the right to use. Free playback improvements: - Drag the playback progress bar to seek through a book. - Use Control Center and Lock Screen playback controls. - Improved recovery after audio interruptions and AirPods changes. Optional Sources with ShelfDrop Pro: - Connect to your own Audiobookshelf or WebDAV server. - Browse and stream supported DRM-free audiobooks from your server. - Download books to Library for offline listening. - Continue listening with Audiobookshelf progress sync. Check server compatibility for free before unlocking Sources. Try Sources free for seven days, with no automatic charge or subscription, or buy permanent Pro with a one-time purchase. Permanent Pro supports Family Sharing. You provide your own compatible server and audiobook files. After the trial ends, Sources requires permanent Pro. Completed local downloads, imported books, listening progress, Files imports, Wi-Fi Receive and local playback remain available without Pro. ShelfDrop does not require a ShelfDrop account. Optional Sources uses your server login; connections and Audiobookshelf progress go directly to your configured server.
