Do you want to learn a new language? Mathematics and physics formulae? History, philosophy or geography? If you need to memorise any kinds of information, Spaced will make it easier and faster.
Spaced hinges on three main principles to help you memorise information: Effort, Short-term repetition and Long-term repetition. Combined with a flashcard system, these three elements will enable you to learn information on the long term by spending five to ten minutes revising each subject regularly.
The first pillar of Spaced's method is Effort: it will make you learn actively and requires you to focus entirely on what you're learning. Instead of only reading questions and assuming you know the answer, you need to type it before unveiling the solution. It forces you to phrase and explain your answer clearly and prevents you from making mistakes you would normally gloss over, such as tricky spelling rules or signs and brackets.
The second one is Short-term repetition. Each training session consists of ten flashcards, and our objective is to make you master most of them in the short term. That's why Spaced will ask you to find the solution of each card three times. You may think this technique will make learning too repetitive and boring, yet it will help you create automatisms. Of course, you can change the number of Repetitions in the settings according to your confidence with the cards you are studying.
Short-term learning is crucial, but the ultimate goal of Spaced is to help you memorise information in the long term. To help you attain this objective, we implemented an algorithm that leverages the famous "Spaced repetition" technique. Whenever you want to revise a subject, the application puts together a Training Set, which consists of flashcards that you need to study as well as new ones you should start learning. To help our Algorithm select the flashcards you should revise, it assigns each one with a Phase and a Score. When you start learning a new card (Phase 1), we'll ask you to study it on an almost daily basis to make sure you know it well. If you succeed, the card will access Phase 2: you still have to revise it regularly to avoid forgetting it, but it won't appear as frequently as before. In the following phases, we will show it less and less regularly: once per week, once every two weeks, once per month…

Of course, Spaced will never replace real-life applications of knowledge: it instead helps you become more and more comfortable with contents you want to learn about and will ward off the stress and anxiety that would loom over you before exams. It is a simple and efficient technique that helps you be more confident and productive and to take advantage of your time spent commuting, between two classes or before sleeping.
