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 classrooms to flexibly assign decks to students. Register as many teachers and admins as you need to divide the workload.
Get a bird's-eye view of who's not studying or which cards students often forget. Or drill down to the details of who answered which cards incorrectly, when and how. Find out what students are struggling with and provide feedback.
No installation. No synchronization between devices. Directly access your cards with a simple, modern web application on an Android, iPhone, iPad, Mac, or PC. (* Mobile access is currently supported only with student features.)
Teachers can create decks to have students memorize anything from foreign languages to maps and chemical symbols.
Multiple-choice cards are supported in addition to standard front-back cards.
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 simple yet powerful markup language called Markdown, which allows you to easily 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 notifications when they have cards due for review. Just have them set the time of day at which they wish to be notified.
Students can do last-minute reviews immediately before exams using a special mode for reviewing only the worst-performing cards.
