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.
