Note of the Day: Sing Today’s Note
One note a day, the same for everyone. Press play, hear today’s note, then sing it back and hold it while your microphone reads the pitch and shows how many cents sharp or flat you are. Any octave counts. You get three tries and your best one counts, then share a result line with coloured squares, like a word puzzle, and keep a daily streak. It runs in the browser with no account and no download, and nothing is recorded: only the pitch is read. A new note every day.
