What's New in Continuum

3.0

October 27, 2026

No more linking chapters one by one. Import your ebook and your audiobook: Continuum lines them up for you, the text highlights with the narration and the page turns itself. IMMERSIVE, NOW AUTOMATIC • Chapters in compatible, chaptered files are matched automatically, and every match can be reviewed and adjusted. • Automatic highlighting follows the narration while you read and listen. • Automatic page turns keep the narrated passage in view. • Choose the highlight color or turn it off. • Smoother transitions between reading, listening, and Immersive, with compact controls and chapter references for both text and audio. A MORE PERSONAL READER • Import your own TTF and OTF fonts. • Highlight phrases and paragraphs, choose colors, and add notes. • Find your highlights and notes alongside your bookmarks. • Line spacing now holds, even where the book's own formatting used to override it. YOUR LIBRARY ACROSS DEVICES • More iCloud support for library, progress, bookmarks, annotations, and chapter links. • Store imported EPUB and audio files in iCloud Drive and recover them on another device. • Clearer messages about file availability, downloads, and recovery. MORE USEFUL STATISTICS • Revised weekly, monthly, and yearly activity, with a calendar and per-book detail. • Clearer reading, listening, and Immersive breakdowns, with share and streaks. • Immersive time is no longer counted twice, and past periods now add up. IMPROVEMENTS THROUGHOUT • Refreshed library, book details, reader, and controls on iPhone and iPad, in portrait and landscape. • Revised dark mode, clearer menus and dialogs, better text layout. • Clearer EPUB and audio import, updated welcome, and practical help. For automatic Immersive, use matching editions with chapters in both files. Initial preparation takes some time. Continuous audio without chapters does not sync reliably. iCloud recovery requires a copy in the cloud. Connect external audio folders on each device. * Books are not included. Bring your own legally obtained, DRM-free EPUBs and audiobooks. Continuum does not supply books, provide a service for obtaining them, or remove DRM. The purchase unlocks app features only.

Does not sync

Does nothing better than just listening on a audiobook player and opening the book on a epub reader. Useless

Response from developer

I’m sorry syncing didn’t work for you. Continuum 3.0 is now available with automatic chapter matching, highlighting that follows the narration, and automatic page turns. It needs matching EPUB and audiobook editions with chapters in both files, and initial preparation takes a few minutes. If your books still won’t sync, please email social@cotinuumreader.app with the title and file formats so we can help investigate.

Extremely buggy. Baffling UI decisions. Primitive functionality.

It’s just an EPUB viewer with an audiobook player in the background. It doesn’t scroll through pages as the audiobook plays as you might expect. Based on the way it was advertised I thought it might use AI or something to sync the words with the audio — similar to a TTS app. But it doesn’t even scroll pages automatically. And there are a lot of bugs. Perhaps my bad experience is because I happened to use an M4B without any chapter markers. Perhaps it might work better with a different M4B. But I lost all patience with it.

LOVE IT

This app is incredible for the price! upload your own files and you can read up to 10x when most apps can’t offer more than 2-3x. Additionally being able to add the epub and follow along is excellent if you don’t mind turning the pages yourself :) works on ipad beautifully and hopefully apple watch one day

Response from developer

Hi, thanks for the kind words on the concept! Great news, the next update bumps playback speed all the way up to 10x, with a manual fine-tune so you can dial in exactly the pace you want. It's already on its way. Hope you'll enjoy the faster listening! Continuum App - team

Needs higher playback speeds

would instantly give 5 stars if the playback speed could go 4x or higher, love the concept though :)

Doesn’t Work

I paid for the app, but it didn’t work. Loaded both my epub and m4b audio files, but it wouldn’t play the audio file. The audio file plays fine in every other app.

Response from developer

I’m sorry you paid for an app that couldn’t play your audiobook. The M4B import issue was addressed in an earlier update, and Continuum 3.0 now includes further improvements to import and playback. If that particular M4B still fails, please contact social@continuumreader.app with your iOS version and what happens when you open it. I’d like to help resolve it.
