## Where Anki stands out

- **Open source** — 1 of 6 apps with a verified answer have this

## Overview

- **Who it's for**: Anyone memorizing information for the long term — students, medical/language learners, professionals studying for exams — who wants a more efficient alternative to re-reading notes or generic flashcards.
- **What you get**: A free flashcard app that schedules reviews using a spaced-repetition algorithm, showing you cards right before you're about to forget them. Cards can include text, images, audio, video, and scientific notation, and decks scale to well over 100,000 cards without slowing down. A large ecosystem of user-shared decks and add-ons lets you start studying a subject immediately or extend the app's functionality.
- **How it works**: You create or import decks of cards, then review them; after each card you rate how well you recalled it, and Anki uses that rating to calculate when to show it again. Anki runs on Windows, macOS, Linux, iOS, and Android, with the free AnkiWeb service syncing your collection across all devices.
