Almost perfect as a basic introduction BUT...it's not always clear what the pictures are meant to be&there aren't that many hangul (Presumably because this is aimed at kids). I can't believe it's free, either! If it wasn't for the few little niggles mentioned above, this would most definitely be 5. Also, if it's not too much trouble, a future edition with more complex hangul for older children would be nice.

won't work, won't zoom out
