Play a phrase and the app finds the scales that contain those notes: tap the microphone by the search field, or type the note names. Play slowly, one note at a time. It also names the chord.

It now speaks French, Spanish, German, Italian, Japanese and Chinese, and you can search scales in your own language.

Many scales carry the name they are best known by, and results say which name matched.

Also: scales one note away, numbered frets, QR code on sheets.
