Tandem Books
Read and listen, in sync.
Free
Read your book. Listen to it. Switch back and forth without losing your place.
Tandem pairs your ebooks with your audiobooks. Start a chapter with your eyes on the train, tap once to continue with your ears on the walk home. Your place follows you between reading and listening.
BRING YOUR OWN FILES
No bookstore lock-in. Import any DRM-free EPUB ebook and pair it with a matching M4B or MP3 audiobook. Tandem works with files you already own.
SWITCH WITHOUT LOSING YOUR PLACE
Tap once to switch from reading to listening, or the other way. Tandem uses short audio transcription to line up the ebook and audiobook, then remembers those positions on your device so repeated handoffs in the same area are faster.
MADE FOR READING
A warm paper surface with a beautiful serif typeface. Adjustable size and spacing. Full-screen immersive mode hides every distraction so you can stay with the book.
ONE UNIVERSAL APP
Buy once, use it on iPhone, iPad, and Mac. Built natively for Apple platforms using SwiftUI.
PRIVACY FIRST
No account required. No sign-up. No analytics. Your books live on your device. The only time Tandem ever touches the network is a brief audio transcription when you switch modes — and even that data is never stored.

Ratings & Reviews
Fixes the multi-track audiobook merge that hung indefinitely when importing 2+ audio files from a folder. If you tried to bring a chapter-per-file audiobook into Tandem and the import never finished, it works now — fast, with chapter markers preserved.
