Catlangu - Learn English

Practice Speaking English

Free · In‑App Purchases

Everything you need to speak English fluently, in one app. Learn 1,500 common English words, practice with AI, talk to real partners, and master English by shadowing. You can read it. You can hear it. But the moment you try to speak — silence. That's not your fault. Most apps teach you to recognize English — not speak it. Catlangu is different. Just 1,500 essential words handle 90% of daily English — and we teach them the way they actually stick: in real sentences, with audio, typing, and live pronunciation feedback. Then we put you in front of real people, so you can finally use what you've learned. HEAR. TYPE. SAY. Every word lives inside a real sentence. Hear it spoken by a native, type it letter by letter, then say it out loud with real-time pronunciation scoring. That's how English vocabulary turns into English speaking. PRACTICE ENGLISH WITH AI Talk with Ava, your AI English partner. Have real conversations whenever you want — no teacher, no schedule, no judgment. Build speaking confidence on your own time. ROLEPLAY REAL-LIFE SITUATIONS WITH AI Practice English in the moments you'll actually live — ordering coffee, asking for directions, booking a taxi, handling a job conversation, debating ideas with a friend. Ava, your AI partner, plays the role and you practice the conversation, over and over, until it feels natural. INSTANT VOICE CALLS WITH REAL PARTNERS One tap and you're in a live voice call with a real English learner from somewhere in the world. Quick Match pairs you instantly — perfect for when you just want to talk, right now. LANGUAGE EXCHANGE — YOU TEACH, THEY TEACH Send an exchange invite to any partner. You help them with your language, they help you with English. Real exchange. Real progress. Real friendships. DIRECT MESSAGES + VOICE NOTES + GRAMMAR FIX Chat 1-on-1 with your language partners. Send text, voice messages, or jump into a private voice call when you're both ready. Every message you write gets instant grammar correction — so you learn from real conversations, not just textbooks. SHADOW ANY YOUTUBE VIDEO Turn any YouTube video into your private English lesson. Pick a clip — a TED talk, a movie scene, your favorite YouTuber — and repeat sentence by sentence. Improve your accent, your listening, and your confidence all at once. YOUR DAILY ENGLISH COMMUNITY A feed full of voice posts, tips, and real conversations from English learners around the world. You're never practicing alone. PRACTICE ENGLISH IN GROUPS Public English groups, open 24/7. Chat, send voice notes, and learn together with people on the same journey as you.
