Cardex: Flash Study Deck

Cardex is a flashcard app built for anyone who wants a clean, distraction-free way to memorize and review material. Whether you are studying for an exam, learning new vocabulary, or drilling through facts, Cardex keeps the process simple and focused.

Create your own decks on any subject, add as many cards as you need, and flip through them one by one with a smooth 3D animation. Each card shows the question on the front and the answer on the back. Mark cards as known or still learning to track your progress through a deck.

All your decks are stored locally on your device. No account required, no sync, no internet connection needed. Open the app and start studying right away.

The interface supports light, dark, and system themes, so it works comfortably in any lighting. A PIN lock option keeps your content private if you share your device.

Cardex is designed to stay out of your way. No ads, no upsells, no unnecessary features. Just cards, decks, and a clean study experience.
