The study tool centers around the concept of a deck of cards. You start out with five kana cards in your reading and writing decks: A, I, U, E, and O. You can add or remove cards from your reading and writing decks as you progress. Your progress with each card can be viewed in the EDIT READ DECK and EDIT WRITE DECK screens. When you are ready to study, choose PRACTICE READING or PRACTICE WRITING. The cart does not check your work automatically, and instead it is up to you while studying to follow the instructions and be honest about your attempts. The cart will remember your last 10 attempts with each card and your progress bar will fill as you get closer to having 10 successful reads out of 10 or 10 successful writes out of 10.
When it comes to writing, the default controls can be tricky, but if you are familiar with Shodo, it is very similar. Many thanks to Ryosuke Mihara for his inspirational cart!
Thank you for checking out my cart, and happy studying!
