About this app

Catii is the English learning app that teaches you to truly UNDERSTAND words — not just memorize them. Learn English for work, daily life, and exams with your adorable cat companion.

WHAT MAKES CATII DIFFERENT?

Most English learning apps make you grind multiple-choice quizzes and memorize word lists. Catii takes a completely different approach: learn through understanding.

Every day, you go on a short learning journey:
1. CHOOSE WORDS: Swipe through word cards (like Tinder) and pick what you want to learn
2. REAL CONTEXT: See each word in a real sentence. Guess the meaning yourself — if you're wrong, Catii explains kindly why, and breaks down the word structure so you can figure out new words on your own
3. PRONUNCIATION: Listen and speak — AI scores your pronunciation and your cat companion reacts to how you do
4. MEMORY GAMES: Play association games to connect words with topics, building deep long-term memory

ENGLISH FOR YOUR CAREER
Catii focuses on practical English for working professionals: office vocabulary, business English conversation, marketing terminology, finance English, and daily communication. This isn't textbook English — it's English you'll actually use at your job.

LEARN LESS, REMEMBER MORE
