Your ebook and your audiobook, synced on their own. Import both and Continuum matches the chapters for you. The text highlights along with the narration and the page turns itself. Your own files. One purchase, no subscription. Read, listen, or do both at once in Immersive mode. On iPhone and iPad. Some books are hard to put down. A chapter on the sofa. Another on the way. Or a quiet moment following the words as you listen to the narration. Listening is reading, too: you choose how to step into the story. IMMERSIVE, AUTOMATIC With chaptered EPUBs and audiobooks, Continuum links the chapters by itself, so you no longer have to match them one by one. Highlighting follows the narration word by word, and automatic page turns keep the passage in view. Choose the highlight color or turn it off. You can review and adjust any chapter link. YOUR BOOKS, NOBODY ELSE'S Import from Files or from a compatible Calibre library. Browse as a shelf or a list, and organize by title, author, and series. Read and listen offline when the files are on your device. MAKE EVERY PAGE YOUR OWN Adjust font, size, line spacing, margins, and background. Import your own TTF or OTF fonts. Highlight phrases or paragraphs, pick a color, and add notes. Revisit your annotations and bookmarks, search inside the book, or move through its chapters. Scan a page of your print copy to find that passage in the EPUB. FULL-FEATURED AUDIO Play M4B, MP3, and M4A. Adjust speed, set a sleep timer, and navigate by chapter. Background playback, Lock Screen controls, and CarPlay. ON IPHONE AND IPAD iCloud syncs your library, progress, bookmarks, annotations, and chapter links. Store imported EPUB and audio files in iCloud Drive and recover them on your other device. External audio folders are connected on each device. Imported fonts stay on the device where you add them. YOUR READING RHYTHM Weekly, monthly, and yearly activity, a calendar, streaks, and time per book. Reading, listening, and Immersive are counted separately, with the share of each. A SPACE FOR YOUR BOOKS A refreshed interface, revised dark mode, and portrait and landscape layouts. ONE PURCHASE, NO SUBSCRIPTION Unlock Immersive, reading, and listening with a single in-app purchase. No recurring fees. Restore your purchase with your Apple Account. WHAT IMMERSIVE NEEDS Matching EPUB and audiobook editions, both with chapters. Initial preparation downloads a model and takes a few minutes the first time. Continuous audio without chapter markers does not align reliably. * Books are not included. You bring your own legally obtained, DRM-free EPUBs and audiobooks. Continuum does not sell books or offer a catalog or service for obtaining them. It does not open DRM-protected files or remove DRM. The purchase unlocks app features only. Books shown in the screenshots are in the public domain. Terms of Use: https://continuumreader.app/terms.html Privacy: https://continuumreader.app/privacy.html

Verdict

The call

The clearest difference is review sentiment: Ink&Echo at 100% against Continuum's 50%. Ink&Echo also leads on rating (4.8 vs 3.0) and ratings volume (22 vs 4). Continuum's advantage is monetization model (free vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.
