LUMO: Learn & Memorize

Your words, your decks. Auto-translate, listen, swipe to learn, track progress — and pick up on any device. Paste a word list and start learning in seconds. Free, no ads.

LUMO helps you build vocabulary your way: with personal flashcard decks, instant translation, and a study flow designed to keep you moving. Create collections for any topic: travel phrases, exam prep, work vocabulary, or words you pick up every day. Type a word, tap Translate, and your flashcard is ready. No switching apps, no copy-paste.

STUDY THAT STICKS • Flip cards to reveal the translation • Swipe right when you know it, left when you need more practice • Cards you’re still learning stay in the deck until you master them • Reverse mode — practice from translation to word • Built-in pronunciation: hear words and translations while you study

ORGANIZE YOUR LEARNING • Group words into custom collections • Filter decks by status: New, In progress, or Learned • Track total words and how many you’ve learned • Study again anytime to refresh a finished set

WORKS WITH YOUR LANGUAGES Choose source and translation languages including English, Spanish, French, German, Italian, Portuguese, Russian, Polish, Japanese, Korean, Chinese, Turkish, and Arabic. Set your preferred language pair once and build decks faster.
