About this app

OTO Navi is an app for listening to audio material provided with books published by The Japan Times Publishing, Ltd. Before, this material was available only through supplementary CDs or MP3 file downloads, but now OTO Navi lets you use your smartphone or tablet to listen to it anywhere, anytime!

●How to use OTO Navi●
It’s three easy steps: 1. Search for the book / 2. Download the audio material / 3. Play it!

1. Search for the book
You can easily search the database for the target book by either entering a keyword (title, author, or ISBN) or scanning the bar code (or QR code) on the book you own. If searching by bar code, scan the upper bar code of the two printed on the book’s back cover.

2. Download the audio material
You can download either the full set of audio material for the book, or just the sections you want. If downloading the full set, you may want to use a WiFi connection.

3. Play it!
OTO Navi offers several handy playback features to aid your studies, including 3-second skipping back/forward and repeating of a single track, a single section, or all sections.

The app does what it claims and it does it well. I think it could be better if I could bookmark individual sections of a book instead of just the entire book. That way I could bookmark any files I need and listen to and cycle through only the specific ones I need.

Whenever I try to download any of the audio files, the app instantly cancels the download. All of the book pictures are missing and replaced with an exclamation mark icon instead. I also tried to open the FAQ shown in the app and it led me to a page which said "Page Not Found". Edit: The app is now working but still no reply to my email so other people with the same problem won't have a fix.

Solid app, I'm not sure what is going wrong for other users. I installed the app and used the built in barcode scanner to scan the top right barcode on the back of my Genki book. It then pulled the relevant audio files. I have now downloaded lesson one and two and am listening to the audio with no issue. Very well designed, easy to use and navigate.
