Mntra — flashcards that stick.

A modern flashcard app with spaced repetition. Cards resurface when
the scheduler thinks you're about to forget them, not when you tap a
button.

Why Mntra

• Swipe or tap. Each card takes one gesture. Right if you got it, left if you didn't ... just like the other App ;) ... or one of four tap buttons when you want more nuance (Again / Hard / Good / Easy).

• SM-2 spaced repetition. The classic algorithm shows you each card at the interval that best reinforces memory. Your review time goes to the cards that need it most.

• Your flashcards stay on your device. No sign-in, no account. Decks, notes, audio, and images live in private app storage. Export any deck as a .mntra archive for backup or sharing.

• Any subject. Language vocabulary, med school, biology, history, trivia, recipes — whatever you want to remember. First-class support for languages (country-flag icons, system text-to-speech, per-side language settings); the rest of the app doesn't care what you're learning.

• Designed, not retrofitted. Dark mode, Material 3 design, lavender accents.
