The average person sends close to 100 messages a day. KeyFluent turns every one of them into a chance to learn a new language. No lessons, no streaks, no extra time carved out of your day. Just type the way you always do, and watch a new language come to life right above your keyboard. TRANSLATE AS YOU TYPE Your message is translated above the keys as you write it, in over 130 languages, from Spanish and French to Japanese, Mandarin, and Hindi. Send it in the new language with one tap, and pick up the words just by seeing them every day. READ AND REPLY IN THEIR LANGUAGE Copy a message you can't read and switch to KeyFluent. The translation is waiting above the keys. Your reply goes out in their language automatically, then the keyboard switches back to your usual language when you're done. TALK FACE TO FACE The new Conversation screen turns your phone into a translator between two people. Each of you speaks, and the other hears and reads it in their own language. Scroll back through the chat anytime and save any line as a flashcard.

The call
