Hey, everybody! Mina san!
Well, i have a samsung galaxy fame with android jelly bean, so I found this amazing app in Google PlayStore, that is the one that i used as a beginner, it has hiragana, katakana, kanji, numbers, grammar and particles (and they are great for begginer and for advanced ones), with their respectives tests. And guess what...
IT'S FREE!!! Hahaaha its name is
Obenkyo and, as you can see, I highly recommend it.
Best Japanese app ever.
Thanks for your time!
Minasan kanbatte kudasai!!
