Nihongo Daily is an educational Japanese word remembering game that can be played everyday to help you remember more words than just straight cramming, alone.
The heart of the game is the daily quiz, which you can do more than once per day if you feel like it. Using a spaced repetition model you are shown a Japanese word in Romaji and are given both the Hiragana and Katakana of this word.
You have ten seconds before to remember what this word means. After the ten second has expired, you are shown the English answer.
Nihongo Daily will keep a track of which words you got correct and which you didn't and will show you these words at different intervals to make sure you're remembering.
Use Nihongo Daily everyday and build a day learning streak.
