3 stars: I was enjoying a lot untill the latest update. The new sounds are brash and annoying and put me off wanting to continue using the app. The previous sounds were very nice and soothing.
2 stars: Good app, the style is very neat, and it has a good purpose, but... 5 minutes per day just sounds not just too little for one to learn the words, but to pay attention about what they are doing, you are desperately looking for the word that represents the image, being more concerned about the time that you spend, that about if you understood what that word really meant, and what does the hiragana or katakana in that word stand by.
2 stars: The Chinese first radicals lesson has 5 pronunciation mistakes. The voice doesn't match the pinyin. And yes, it's weird that you have an app for each language even though you can learn all the languages on the Japanese one.
