Flixdex

Flixdex is a local flashcard app built around smooth 3D flip animations. Create study decks on any subject, add cards with questions and answers, and review them with an interactive flip effect that makes memorization feel engaging rather than mechanical.

Everything runs on your device with no account needed. Your decks and cards are stored locally, so you can study offline anytime.

The app includes multiple named themes — two light and two dark — so you can pick a look that suits your environment or mood. Font size can be adjusted across three levels, and haptic feedback can be toggled for a more tactile study experience.

On first launch, a short two-screen onboarding explains how to create decks and start reviewing. After that, you go straight to your cards.

Decks are organized in a tab-based layout. Swipe between sections to browse your collections, review active cards, or adjust settings. Empty states animate gently so the interface never feels broken or abandoned when you're just starting out.

There are no ads, no purchases, no sign-ups, and no data sent anywhere. Flixdex is a straightforward study tool that stays out of your way.
