About Anki
Anki is a flashcard program that uses spaced repetition, showing you each card just before you are likely to forget it. It is widely used for languages, medicine, exams and any subject that needs long-term memory.
The desktop application is open source under the AGPL-3.0 licence and runs on Windows, Mac and Linux. Cards can include text, images, audio and video, and a large library of shared decks and add-ons extends it. AnkiWeb syncs your collection between devices. On Android, the free and open-source AnkiDroid app is a separate community project, while the official iOS app is a paid purchase listed at $24.99.
It suits students and self-learners who want an efficient review system and do not mind a plainer interface. The desktop version is free, and the iOS app price helps fund the project. A recent Windows release notes an important security fix and asks users to upgrade to version 26.09 or later. Creating good cards takes some effort, so it rewards people who build their own decks.
Update to version 26.09 or later on desktop because it includes security fixes. The Android app, AnkiDroid, is a separate project from the desktop software.
