From the Kickstarter Campaign:
KIOKU is a portable flashcard system that makes learning Japanese both effective and convenient—anytime, anywhere. After our first Kickstarter for KIOKU Kanji Cards was backed by over 1,300 supporters, raising 120,000 dollars, we knew we had tapped into a worldwide need for on-the-go study tools. Now, we’re expanding that proven method to Vocabulary and Grammar, creating a comprehensive Japanese learning solution in one pocket-sized format. (Source: Kickstarter.com)
