Reference pitch: The tuner lets users set A4 from 400 to 480 Hz.

Accuracy method: The tuner uses the McLeod Pitch Method with parabolic interpolation for sub-cent resolution.
Strobe tuner: The browser strobe tuner is described as resolving differences down to a fraction of a cent and supporting intonation checks.
