iPhone
Your audiobooks, your way. Marginalia is an easy to use player for files you already own. Import from your computer in seconds.
Marginalia is a full-featured audiobook player built for people who own their own files. Whether your library
comes from Libro.fm, Humble Bundle, CD rips -- Marginalia plays it beautifully.
EFFORTLESS IMPORT
Getting books onto your phone should be easy. Marginalia gives you three ways:
- Share Sheet: Share a zip file or audio files from any app and they're instantly extracted and ready to play.
- Wi-Fi Transfer: Open the built-in web page on your computer's browser and drag-and-drop files — no cables, no cloud
accounts.
- Files App: Import directly from iCloud Drive or any file provider.
ROCK-SOLID PLAYBACK
- Plays MP3, M4A, M4B, AAC, and FLAC files
- Chapter navigation for M4B files and multi-file audiobooks
- Playback speed from 0.5x to 3.0x
- Adjustable skip forward and back intervals
- Background audio with Lock Screen and Control Center controls
- Your position is saved automatically and survives app restarts
- Smart rewind — picks up right where you left off, rewinding a few seconds based on how long you were away
SLEEP TIMER
- Duration presets and end-of-chapter stop
- Gentle fade-out so you're not jarred awake
- Auto-restarts when you resume the next day
VOICE NOTES
Hold the mic button to record a thought while you listen. Your note is linked to the exact playback position. Tap it
later to jump right back. Add Assembly.AI transcription with your own API key to make notes searchable — then export
everything as a clean Markdown document.
