Leksi: language flashcards

leksi is a simple, effective flashcard app for learning vocabulary in any language.

Add words and their translations, then let leksi decide when to show them again. It uses the SM-2 spaced repetition algorithm — the same method used by memory researchers — to surface cards right before you're about to forget them. The more you know a word, the less often it appears. Struggle with one, and it comes back sooner.

Features:

• Create decks for any language pair — or monolingual decks for definitions
• Add word and translation pairs in seconds
• Smart review scheduling powered by spaced repetition
• Filter and sort your word list by date, alphabet, or review rating
• Review across multiple languages in a single session
• Lightweight and offline — no account required

Whether you're preparing for a trip, studying for an exam, or just picking up a new language for fun, leksi keeps your practice focused and your time well spent.
