Learn a language by talking your way through everyday scenes. Line drops you into real situations, a café, a hotel check-in, a job interview, a night out, and puts you in a real conversation with a character who listens and talks back in real time. No flashcards, no scripts. You speak, they answer, and you keep going. A GUIDED PATH Every unit teaches the phrases first, then hands you a scene to use them in. Learn, speak, listen, recall: short lessons you can hear and repeat, with pronunciation feedback on every word you say. SCENES FROM REAL LIFE Greetings, ordering food, getting around, shopping, work and study, health, making plans, telling stories about your travels. Each scene has its own character and goal, and the ones you care about rise to the top. HELP WHEN YOU WANT IT Tap for a translation or a suggested reply, and put your phone down when you do not need it. The character keeps the conversation moving at your level. FOURTEEN LANGUAGES Spanish, French, Portuguese, German, Italian, Dutch, Swedish, Polish, Russian, Turkish, Korean, Hindi, Indonesian and Vietnamese. TRY IT FREE Start a free trial on the yearly plan and speak your way through as many scenes as you like. Line Pro unlocks every scene and lesson in every language. Subscriptions renew automatically until cancelled and are managed in your Apple ID settings. Sign in with Apple or Google and start speaking today.

Verdict

The call

ReceptionRating · Positive reviews · Number of ratings

Superfluent Classic holds the better App Store score, 4.6 against 3.9. Both are backed by a comparable volume of ratings — 12 and 7 respectively.

UpkeepUpdate frequency

Superfluent Classic ships an update monthly, Line daily. The most recent releases landed on October 6, 2026 and October 11, 2026 respectively.
