About

Oduetto

Read full description

Oduetto teaches you a language the way a chorus gets stuck in your head. Every song is an original duet, written from sentences you will actually use: ordering a coffee in Rome, gossiping in Paris, asking for directions in Tokyo. Press play, sing along, and let the repetition do the work. Pick a vibe, Coffee Talk, Restaurant, Wine Tasting, Travel, Daily News and dozens more, and get a fresh duet daily, designed to loop until the phrases are yours. SING IT Grab the mic. Duet karaoke rolls the lyrics in both languages while you sing your side of the duet, and every line you sing gets scored. Chase the five stars. PLAY IT Lyric Surf: steer the record into the line you just heard, stack combos, and beat your high score. Lyric Pop: pop the bubble with the line that is playing. Practice: quick quizzes built from verses you already know by heart. FOLLOW THE JOURNEY The Duet Journey arranges your language into ten movements, Overture to Finale. Practice a song to advance, follow what you love when the path forks, and close each movement with a quiz. A gold record waits at the final bar. MAKE IT YOURS Tell Maestro a topic, sailing in Lofoten, aperitivo in Portofino, island hopping in Greece, and get your own duet song about it. LEARN TOGETHER Keep streaks with friends, share loops, and collect medals for showing up. Cast the app to your TV for a karaoke night and sing duets on the couch until the whole room knows the chorus. A Kids page brings gentle sing along songs for little ones. PREMIUM Go Premium for every vibe, unlimited daily songs, and Maestro, your own topics turned into your own duets. LANGUAGES Italian, Spanish, French, German, Portuguese, Japanese, Korean, Mandarin Chinese, Dutch, Swedish, Norwegian, and Swiss German. Use Oduetto alongside your language class, your apps, and your podcasts. Absorb a language through music. On repeat.
