Recur is an Android app for practicing flashcards using spaced repetition. Users can create and manage decks, edit cards (CRUD), and enter a play mode to review them. The home screen provides an automatic feed of cards that are due for practice.
The project focuses on clean architecture, local-first persistence, and a modern Compose-based UI.
