This is the fastest way to learn the kana alphebets. In less then a week i could see any hiragana and know the sound(knowing sound then remembering the symbol is a different story but, thats my learning problem and ive gotten better through practice). It is very simple which adds to how easy it is. I would definately get this app if you are serious about learning japanese.
P.S. for those that want a "night" feature, set your triple click home to white on black and you are good for late night lessons
