OnKey is a free, open-source singing trainer for the Mac. Play a song in Spotify, Apple Music, or YouTube in a browser, and sing along. The first time, you get the lyrics, and OnKey learns the singer's melody when the song ends. After that, the notes scroll towards you, your pitch is drawn over them, and you get a score with a report on every line.

From its README on GitHub

OnKey is a launch on Show HN. It is written in Rust and released under the MIT license.
