Langle teaches the Korean people actually say — one real expression a day, in about ten minutes. A DAILY ROUTINE THAT FITS Every day you get one expression you will really hear in Korea, in dramas and in conversation. A short routine walks you through it: • Listen to it, slowly or at natural speed • Watch it in short clips from real Korean media • Collect the words as cards • Build the sentence yourself from your cards • Say it out loud — speech recognition checks what you said • Use it in a short conversation (on iPhones with Apple Intelligence) CARDS THAT STAY WITH YOU Every word you meet becomes a card in your collection. Spaced-repetition reviews bring each card back right before you would forget it, so your vocabulary keeps growing without cramming. START AT YOUR LEVEL A quick placement check sets your starting level, and the routine grows with you. FEED Browse short clips of expressions you have learned and practise saying them whenever you like. PRIVATE BY DESIGN Speech recognition and voice playback run on your phone's built-in engines, and the conversation partner runs on-device on supported iPhones. Your voice recordings are never uploaded. Questions or feedback: vioin8449@gmail.com
