Narratorio is the first text-to-Speech app that nails the basics and the pro features in one elegant package. Imports anything—PDF, EPUB, slide decks, even comics—in seconds. 80+ natural voices, fully offline—no streaming, no data drain, no cloud connection, no internet. Word-perfect highlighting so I can glance down and pick up exactly where the narration is. Privacy-first on-device processing. Handy controls like ±15 s skip, speed up to 2× (my sweet spot is 1.25×). Now my 45-minute commute becomes a chapter of Emma or the latest clinical guidelines (fellow docs, you’ll love this). If you want dead time to become productive listening time, download Narratorio and reclaim your day.

Amazing Offline Text-to-Speech App!
BookQueenBee
Narratorio is exactly what I was looking for. I use it to listen to PDFs and books, and the text-to-speech feature works beautifully—even offline! The voices are clear and natural, and it makes it so easy to “read” on the go or while multitasking. I really love that I can just load a document and have it read aloud without needing an internet connection. Highly recommended for anyone who wants a convenient way to consume written content hands-free.

I love using this TTS reader offline because I work in airplane mode so not to get disrupted by continuous notifications and emails. This app is a godsend for me.
