Japanese Android App
So I got a smartphone (at last, moving up in the world ha. ha. ha.) and it's been fun playing stupid games on it but I decided I should probably put it to better use now.
Anyone have a suggestion in an app for learning Japanese on the go? I could download everything in the Google Play store and trial-error, but I decided some opinions (if any) would help.
Already know hiragana and katakana, need work on improving kanji vocabulary, as well as learning grammar.
Phone is an LG Optimus G, in case some compatibility issues arise.
