I read fast and listen slow. Some days it’s the other way around. What never changed was how annoying it felt to lose my place every time I switched between the ebook and audiobook of the same story. So I built TomoTomo. The idea is simple: **your ebook and audiobook should feel like one book**, even if you bought them separately. Bring the files you already own, pair them once, and move between reading and listening without starting your search for the right chapter all over again. You don’t need to buy into another library to make your books work together. The hard part is that a place in text and a time in audio are completely different things. TomoTomo connects them in both directions. Read ahead, then press play from your page. Listen on a walk, then open the ebook near the passage you’re hearing. It keeps track through pauses, chapter changes, switching back and forth, and reopening the app. When reliable narration timing is available, Follow Along can highlight the spoken word or passage. When it isn’t, TomoTomo uses the best available match and lets you adjust it. It won’t pretend an estimate is exact. You can also search for a line you remember and use **Play from here** to get back to that part of the story. What it does: - Reads your EPUB and PDF files in a quiet, adjustable reader - Plays your M4B and MP3 folder audiobooks, with lock screen controls, speed settings, and a sleep timer - Pairs matching books and audiobooks automatically, with manual pairing when needed - Carries your place between reading and listening - Follows narration in real time when you want it to - Saves highlights and notes - Keeps imported books available offline There’s an optional companion for talking through a book, and an optional account if you want your place across devices. Neither is needed to read or listen to the files you already have. No streaks. No badges. No login wall between you and your books. Just the freedom to read when you want to read, listen when you want to listen, and keep going.
