Or connect your own library through Audiobookshelf, OneDrive, Google Drive, or Dropbox to browse, download, and listen offline — directly from Apple Watch. Google Drive and Dropbox support are currently in beta. They are available for testing and everyday use, but some files, formats, or account setups may not work perfectly yet. OneDrive and Audiobookshelf are the recommended options if you want the most stable experience.

Works for audiobooks, podcasts, and ambient sounds. * Siri and Shortcuts: Say "Resume Auribook", pause, skip, or start a sleep timer, also from the Action button. * Widgets and complications: Continue Listening with cover and a play/pause button, time remaining, chapter progress, and quick access to the player, your books, and sounds — on your watch face and in the Smart Stack. * Audiobookshelf syncing: Start on your watch and continue elsewhere, or the other way around. Progress stays in sync with your Audiobookshelf server, and your watch picks up where you left off on other devices. * Podcasts: Browse shows and episodes, filter for unplayed items, sort your feed, and download episodes for offline listening. * Ambient sounds: Play relaxing nature sounds and noise colors such as rain, fireplace, white noise, pink noise, and brown noise. * Direct connection: Point Auribook to your Audiobookshelf server URL or connect a supported cloud provider and enjoy your library on your terms. * Private by design: No analytics, no tracking, no third parties.
