Comments on OTO Navi - Sound Navigator for Android
★★★★★Eugene & Rachel Spagnuolo· Jun 11, 2024
Unbelievable. This app is completely changed by Japanese studies for the better. And to be free is just crazy. Between this and Japan times vocabulary and kanji apps, genii Japanese is so much better. It's not a classroom, but it is so much better than just studying the book.
★★★★★Namiko Asuka· Mar 29, 2022
Working as intended with my GENII textbook. Downloads worked well and the audio complements my textbook well.
★☆☆☆☆Joe Lewis· Mar 26, 2020
Scanned the book in. The audio files won't download. I press the button and nothing happens.
★☆☆☆☆Cameron Butler· Nov 9, 2025
App doesn't work. Open it and it just doesn't do anything. No way to add books you're using or even interact with the app.
★☆☆☆☆Greenview Media· Sep 20, 2021
App gives me an error code whenever I open it, and it sits on the main screen. I tried updating but still doesn't work.
★☆☆☆☆Airi· Mar 13, 2021
Can't download some lessons, such as lesson 10 in Genii 1 textbook, which means I can't follow exercises.
