What is Spaced Repetition?

1. Forgetting Curve

The Forgetting Curve

Humans forget newly learned material in a matter of days (red curve) unless reviewed from time to time (green curves).

2. Spacing Effect

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.
Wikipedia .

3. Spaced Repetition

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.

Spaced Repetition for Schools and Classrooms - Features

School and Classroom Management

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.

Monitor Progress

Student progress Monitor students' progress and find out which cards students have difficulty with so you can take appropriate action.


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 with students only.)

Memorize Anything

Teachers can create decks to have students memorize anything from foreign languages to maps and chemical symbols.

Memorize Anywhere, Any Time

The key to memorizing is repetition. Students can use their smartphones to review their cards in their spare time, anywhere, any time.

Memorize "Super" Efficiently

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.

Memorize by Writing

Handwritten answer Students can handwrite answers directly on screen to precisely test their memory and to help them memorize better. Keyboard input is also supported.

Memorize Maps and Pictures

Card with image Add images to your cards to memorize maps, pictures, and drawings.

Format Content as You Wish

Card with superscript and subscript 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.

Card Upload to the Rescue

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.

Receive Reminders

Students can receive reminders when they have cards due for review, specifying the time of day at which they want to be notified.

Exam Preparation

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.
