Cortexio: Flashcards & HSK

Wael Apps

About this app

Cortexio is a clean, focused flashcard app for learning anything, with special tools for Chinese learners.

SMART REVIEW
Rate each card from 1 to 5 by how well you know it. Cards you struggle with come back sooner in the same session, and cards you know well step aside so you can focus on what matters.

UNLIMITED CARDS
Create as many decks and cards as you want. No card limits and no subscription.

ORGANIZED YOUR WAY
Keep decks on their own or group them under subjects. Cards are color-coded by your confidence so you can see your progress at a glance.
