Korean Select Word

Teaching application for Russian people studying Korean language.
Select Russian translations for Korean word (in Hangul) or change mode to
select Korean translations for Russian word. Translations rise as bubbles from screen bottom and are selected
by clicks.
Applications collects words statistics (on device) and tries to show difficult words more and easy words less often.
Words are taken from my textbook which I use to learn Korean, added when I have to learn them. "Korean Vvodnyj Kurs, Won Gwan school, 2009" (on Russian) - http://www.ozon.ru/context/detail/id/15739983/
For me it is easy to start correctly select new words, but to say korean word and then select it is more difficult and better resembles what I have to do before teacher.
You can listen to selected words using Korean Android TTS.
You can switch between Russian and Enlish translations of Korean words in settings menu/ Other language radio group selecting Russian or English other language.
