Spaced helps you memorize anything that fits on a flash card by using the spaced repetition technique.
You start by adding flash cards to the system, in the form of questions and answers. You can use tags to organize this information in any way you like.
Each day you'll be presented with a particular set of cards. Every time you answer a card, you'll be asked to rate your performance, mainly how easy it was to recall the answer. The next time we assign you a set of questions, difficult cards will show up more often than the easier ones. Through constant practice and repetition, you'll eventually build the information from your cards into your memory.
You can use this technique to learn foreign words, phone numbers, historical facts, medical terms, programming languages, keyboard shortcuts and more.
