Immersive Listening

Horizon is designed to disappear. We believe the best interface is the one you don't have to think about, allowing you to focus entirely on the story.

Full Library Sync

The app performs a full sync of your library data. Everything is lightning-fast—filtering, search, and book/series details are instantaneous. Start listening immediately if your book is downloaded. Your progress is synced instantly, or saved locally if you're offline until you reconnect.
