Requirements: 5.0+
Overview: AnkiDroid lets you learn flashcards very efficiently by showing them just before you would forget. It is fully compatible with the spaced repetition software Anki (including synchronization), which is available for Windows/Mac/Linux/ChromeOS.
Study all sorts of things wherever and whenever you want. Make good use of idle times on bus trips, in supermarket queues or any other waiting situation!
Create your own flashcard decks or download free decks compiled for many languages and topics (more than 6000 available).
Add material through the desktop application Anki or directly through Ankidroid. The application even supports adding material automatically from a dictionary!
