Worth noticing: Reference tones pause microphone detection, and targets update for 440 Hz, 442 Hz, or a custom reference.

Field notes

Users can select G3, D4, A4, or E5, or let the page identify the string, then watch a pitch reading while making small adjustments. The reference is set to A4 = 440 Hz by default; Settings also offers 442 Hz or a custom value, and the page supplies short reference tones. Its guidance covers jumping readings, fine tuners versus pegs, and when a beginner should ask a teacher for help. The site says microphone audio stays on the device.
