Rikaikyun is a Phonegap app for reading Japanese text and was based on Rikaichan\Rikaikun (I used one of the core files from Rikaikun, but it appears to be no different from the original Rikaichan). At its core it uses EDICT (I used the modified files from Rikaikun which again likely are the same as in Rikaichan).
This app was made because the existing Jade Reader was missing a number of features (and I know too little about JAVA to make any major changes). The key ones:
This app is somewhere in alpha stage, meaning some of planned features are still not implemented (though all of the above are already there). Some of the planned features include:
Nonetheless even at the current stage the application should be usable.
GPLv3 (because Rikaikun\Rikaichan were licensed with that)
This project also uses a number of compatible open-source licensed libraries and I retaind information on their licenses (where it was possible).
I'm inclined to publish this on a less restrictive license than GPLv3, but it will require me to rewrite the core Rikaichan file (loading dictionary, parsing it, deinflection, dictionary look ups).
