What is SRS?

SRS (Spaced Repetition Software) is a type of software designed specifically for implementing spaced repetition, an evidence-based memorization technique where flashcards are reviewed at gradually increasing intervals of time. This technique takes advantage of the spacing effect and temporal decay of memory to dramatically improve knowledge retention over traditional memorization methods.

SRS software typically allows users to create digital flashcards with questions on one side and answers on the other. An algorithm then schedules these flashcards to reappear for review at optimal time intervals based on the user's performance. Getting a flashcard correct will increase its review interval, while getting it wrong will decrease the interval. This adapts the review schedule to focus on each user's weaker areas.

By repeatedly reviewing flashcards in this fashion, users are able to efficiently memorize large amounts of information over time while minimizing forgotten details. Popular subject areas for SRS flashcards include foreign language vocabulary, geographical locations, historical facts, medical terminology, and more. However, the technique is flexible enough to apply to nearly any subject that requires memorization.

Well-known SRS platforms include Anki, SuperMemo, Mnemosyne, and Brainscape. These applications are available on Windows, macOS, Linux, iOS, Android, and the web. Most are free and open source. While they share the same core spaced repetition algorithm, they differ in their specific scheduling methods, user interfaces, and supplementary features.

Research has extensively validated spaced repetition as an incredibly effective learning technique. Combined with the convenience of digital flashcards, SRS software allows students, professionals, and lifelong learners to efficiently memorize and retain information in a wide variety of domains.
