On each card there are three columns into which text may be edited, and these have been arranged so that you can edit them while looking at them lined up next to each other. The cards can be formed into groups (stacks). This is a very simple app that just does card-based data handling. Any column can be invisible by one tapping.

How the three columns are used is up to you. As an example, you could make your own Japanese-English translating exercises. The three columns would be "Question in Japanese", "Model answer in English" and "Your answer". Just prepare a set of cards so that each card has a question and a model answer on it. Then, to practice your transration exercises, hide the "model answer" column and type in an English sentence as your response to a question. After that, display the solution (model answer) to check your response.

You can move between cards by means of the arrow buttons or by dragging cards with your finger. It is also possible to move to another card by tapping on the card list. In addition, it's possible to find cards based on a search for bookmarks or the rankings attached to the cards. It's also possible to insert into a column a link to another card and jump to the referenced card by tapping on the URL scheme as link.
