This is a open source text file reader with a built-in offline Japanese-English dictionary for Japanese learner on the go without an active Internet connection for online dictionary. The algorithm used to search for word is taken from Rikaichan for Firefox.

The Japanese-English dictionary is the EDICT dictionary from WWWJDIC. It was converted to a format suitable for Android devices.

Definitions of a word is displayed/translated on the same activity as the text so that the reader does not lose the context of what they are reading when looking for meanings of words.

- Highlight and bookmark functionality
- Save words for future review

Great app but since at least Android 8, cannot change the font size. Pressing the 3 dots at the bottom right that appear after long-pressing anywhere on the screen has no effect - the dots just flash. If this app could get refreshed, I would gladly pay for it. I verified that the "3 dots" menu works on Android 6 and 7. I'm wondering if it is a permission issue.

I would like the ability to change fonts and add different dictionaries, but still an amazing app. Edit: on my new phone I have also run into the bug where the options menu can't be opened. Needless to say, this is a huge problem. Lowered the review to two stars. Edit2: Still, Jade Reader as been a trusty companion on my journey to mastering Japanese for many years now, and there's nothing better out there.

Excellent app, use it everyday. If anything, I just wish it had J-J dictionary support and maybe an option to display text vertically.
