Every reader knows the feeling: you find a book that grips you, and you wish you could live inside its world. For me, that experience becomes exponentially more powerful when I can read and listen at the same time — the narrator's voice gives depth to the words, and the text anchors what I hear.
I searched for an app that would let me do both simultaneously — read an ebook while the audiobook plays, keeping my place in sync across both. Nothing existed. Every reading app treats text and audio as separate experiences.
So I built Continuum.
Continuum is the first iOS app that brings true immersive reading to DRM-free ebooks and audiobooks. Import your EPUB and M4B/MP3 files, map the chapters together with the sync wizard, and switch freely between reading, listening, or both at once. Your position stays perfectly synchronized.
No accounts. No cloud. No tracking. One-time purchase. Your books, your device, your privacy.
Continuum is developed by Undercover Lab, a digital product studio based in the Principality of Andorra. We build tools that respect users — no subscriptions, no data harvesting, no compromises.
