Humans forget newly learned material in a matter of days (red curve) unless reviewed from time to time (green curves).
Humans more easily remember items when they are studied a few times spaced out over a long time span
than when studied repeatedly in a short period of time.
Spaced repetition is a learning technique in which items are reviewed in increasing intervals of time
to make most use of the spacing effect so that they can be remembered effectively and efficiently.
It is especially well suited for memorizing huge amounts of material and keeping them indefinitely in memory.
Register students and decks, and then create classes to flexibly assign students to decks. Multiple admins and teachers may be registered to distribute this task.
See which cards students tend to get wrong and improve by adjusting class content or the deck itself. The average percent-correct for each card can be viewed per class and school-wide.
No installation. No synchronization between devices. Directly access your cards with a simple, modern web application on an Android, iPhone, iPad, Mac, or PC. (* Teachers are currently limited to using either a Mac or a PC.)
Teachers can create decks to have students memorize anything from foreign languages to maps and chemical symbols.
The key to memorizing is repetition. Students can use their smartphones to review their cards in their spare time, anywhere, any time.
With Spaced Repetition, students spend time on those that need it, not on the ones they have memorized. Spend the minimium time required to keep things memorized, super efficiently.
Students can handwrite answers directly on screen to precisely test their memory and to help them memorize better. Keyboard input is also supported.
Add images to your cards to memorize maps, pictures, and drawings.
Card content is interpreted in a lightweight markup language called Markdown, giving you the power to create cards with links, bold text, super/sub-script, etc., tailored to your needs.
Creating cards may be tedious. If you have cards in another system or want to create cards with other software such as Excel, simply import them as a CSV file.
Students can receive reminders when they have cards due for review, specifying the time of day at which they want to be notified.
Students can prepare for exams by focusing on the cards they often forget. Simply specify the number of worst-performing cards you want to review.
