About this app

Import ePub files that are in Simplified or Traditional Chinese and then have them converted to add a romanization line (pinyin, Sidney Lau, Yale), and a native language line (English, Spanish). The document can then be converted to PDF. It is also possible to copy Chinese text and paste it into the app. In addition, you can copy a URL from the Safari web browser, and paste in the URL to pull up the entire web page in the app and then convert it to 3 lines.

I do appreciate this app. It's been very helpful with me trying to expand my ministry and learn Chinese :). My only suggestion would be that instead of having the option to show all pinyin or to show no pinyin... Maybe have the option to be able to delete the pinyin to the characters that we already know. This will be very helpful in helping us to learn the characters more better. A lot of friends have suggested in doing this to force me to follow along looking at the characters and not so much at the pinyin. Right now I have to use Adobe reader to black out the pinyin that I already know and it kind of looks like a mess :(( . It's just a suggestion :)) if you can do it that will be awesome.!!! Thanks for the helpful app. :))

We love this app and have used it for years now. Just recently, we have faced an unexpected problem and wonder if you have any suggestions on how to get around it? Epubs downloaded from our favourite website are now in zip files and, when extracted by our devices, now have multiple files and cannot be opened by your app. We do not know what to do about this, please help!

I am not seeing a difference. They still open for me. It is possible that something caused the file association to change. You can try this: https://portal.smartertools.com/kb/a3585/changing-the-default-app-for-a-file-type-on-android.aspx. You can contact me directly through email at: jonmhargett@gmail.com

Very good epub language translation tool. NB: always asks for Dictionary update each time you open, but never updates when you click to. kindly let me know if i need to do something about that...
