### Learn a new language by chatting with your local friends in your native language! Forget grammar rules. Just chat! You type in your native language, but the text appears in the language you are learning. Learn languages naturally. For example, both you & your friend type in English, but you receive in French! It creates a foreign environment instantly. ### Improve step by step. No language prerequisite How you chat is up to you: Use 100% your native language. (Just act like you are home!) Mix it up. (Combine native and new words.) Use the new language. (Challenge yourself!) Check meanings, listen to how it sounds, and build your vocabulary. ### No awkward Chats. Just fun. You don't need to find a stranger to practice. Chat with Friends: Switch to UM3 with your real friends. Continue your daily chats, and learn a new language in the meanwhile. Find New Buddies: You can also find new friends in the APP, who share the same interests with you. ### Learn any language you like English, French, Spanish, Italian, Portuguese, German, Chinese, Japanese, Korean, Hindi, Arabic, Russian and more.
