Bookmate vs Prologue

Bookmate is a subscription service for reading electronic books and listening to audiobooks, available on Android, iOS, and the web. Its catalog lists 1,800,000 books and 100,000 audiobooks in 16 languages, and it describes a free collection of 50,000 books. Readers can upload their own FB2 or EPUB files for use on a smartphone, tablet, or desktop, then adjust brightness, font, and background color. Social features let users follow friends’ reading, share books and quotes, and create or subscribe to themed bookshelves. Audiobooks can be saved for offline listening and synchronized across devices so listeners can resume where they left off. Bookmate lists a free plan and a seven-day trial; the Premium plan is listed at free. The subscription page describes monthly and annual options but does not show their prices. An account is limited to one person and no more than three devices. Books cannot be downloaded and distributed outside Bookmate.

Prologue is a self-hosted audiobook player for Plex and Audiobookshelf libraries. It can connect to either service or both, with offline downloads, collections, series, bookmarks, a reading list, statistics, and playback history. Playback controls include per-book settings, sleep timers, smart rewind after pauses, Voice Boost, and an equalizer. The maker lists iPhone, iPad, Apple Watch, Siri, widgets, and CarPlay support, with macOS also listed as a platform. Apple Watch can stream books being read or on the reading list, download books for offline listening, and use widgets and complications. Prologue says library data remains on your devices and that it does not store or handle Plex or Audiobookshelf passwords; access tokens are stored on-device. It collects pseudonymous usage and Apple Ads attribution data, and uses Sentry for crash reports that may include device and operating-system details. The App Store listing requires iOS 26.5 or later and lists iPad, Mac with Apple M1 or later, Apple Vision, and Apple Watch compatibility.
