Sensor calibration
Which skin tone is closest to yours? Used only to correct heart rate sensor bias.
Fitzpatrick scale I–VI · Used only for sensor calibration · Never shared

Wearable sensors use green light, which melanin absorbs. For types IV–VI this can cause HR errors of 10–20% during exercise. VITAL corrects for this automatically.
