LUMO: Learn & Memorize

Turn any word list into flashcards in seconds. Swipe to learn, then quiz yourself — multiple choice or typing. Auto-translate, offline sync, 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
