Couplet is a learn-by-ear language app. Each deck distills a real situation ordering dinner, asking directions, a phone call down to the handful of phrases that do ~90% of the work, so you can finish it and actually walk away knowing them.
One quirk people either love or find weird: you hear the English first. In that beat before the native line, your brain reaches for the phrase itself then the answer lands as confirmation or correction. That tiny act of trying-then-comparing is what makes it stick.
French and Japanese are live today with 1,000+ topics. Two questions for you:
Couplet teaches a language by ear, one real-life scenario at a time. Hear each line in English, then in another language— ordering dinner, small talk, a phone number, 1,000+ topics in all. For every topic, a small set of high-frequency phrases covers ~90% of what you'd actually say, so each deck is finite and finishable, not an endless vocab list. No streaks, no feed — play it like a podcast and finish topics in minutes. English→French today; Japanese and more coming.
