Memorize
A study tool with no editor in it. Decks are written straight into the database by the Loader, so nothing has to be typed twice. This application exists only to study them, and to remember how well that study went.
A Deck is an ordered set of Cards, and the order is a teaching sequence rather than an accident. A Learner works through one in a Study Mode. Learn introduces Cards not yet Passed, in Rounds. Rehearse meets Cards already Passed, shakiest first. Flashcards shows everything and records nothing.
Nothing is owed and nothing is overdue. There is no queue counting up while you are busy. The application never grades either — a Learner judges their own recall, and that judgement is the only thing written down.
