App Profile: Word Rep

Hello friends,
This game is designed to help Korean & Japanese learners.
It mainly focuses on words or vocabs or phrases, helping learners to remember words. However, no audio is included.
A method of repetition is applied. Words are organized in packs. A word can be repeated in different packs.
After learning words, learners must take challenges to reinforce what you've learned.
Again, a word can be repeated in different challenges to assure you remember it firmly.
The challenge rule is simple: from a native word, find its meaning in English or reverse.
It is better to know some basics of the language or know at least its alphabet.
Thank You !
