Field notes
The homepage lays out separate Professor and Athlete modes, with paired English and Portuguese examples for warm-ups, technique explanations, and live rounds. It describes microphone-based voice practice, pronunciation feedback, a technical glossary with native audio, and five-minute lessons; the page also claims more than 450 voice simulations. These are homepage descriptions rather than independently verified app behavior.
