Master vocabulary the way that works for you. FlashFocus combines interactive flashcards, quizzes, and audio exercises into one fast, focused study tool — and it all works offline.

STUDY YOUR WAY
Flip through flashcards at your own pace, toggle between showing the target language or English first, and reveal pronunciations when you need them. Every card plays audio with clear text-to-speech so you hear the correct pronunciation every time.

TEST YOURSELF IN SECONDS
Switch to Knowledge Check for three rapid-fire modes: Multiple Choice, Word Matching, and Listen & Choose — where you hear the word and pick the translation. Instant feedback keeps sessions short and effective.

BUILD OR DOWNLOAD DECKS
Create custom cards with a word, pronunciation, and translation, then organize by level and category. Or browse the FlashFocus library to download curated vocabulary sets and start studying immediately.

STAY ORGANIZED
Search your full collection, filter by level, category, or favorites, and jump straight to the words that matter. Mark any card as a favorite for focused review sessions.

TRACK EVERY SESSION
See all-time stats — cards studied, total correct, and accuracy — alongside daily progress. Keep your study streak alive with daily reminders and celebrate milestones.

WORKS COMPLETELY OFFLINE
Study anywhere with no internet required. Your cards, stats, and progress live on-device and sync automatically when you reconnect.

NO ACCOUNT REQUIRED
Start studying as a guest with full access. Create an account later to sync progress across devices — all your data migrates seamlessly.

LANGUAGES: Simplified Chinese (with Pinyin), Japanese, Hindi, Urdu — more coming soon.
