A state display apparatus includes a display section that displays a state of a measurement target subject based on biometric data of the measurement target subject; and a control section that performs control such that a display mode at the time of displaying a state of the measurement target subject next time onwards is changed so as to be different from a display mode at the time of displaying a first state based on first biometric data of the measurement target subject, in a case where second biometric data acquired at the time of displaying the first state on the display section satisfies a predetermined condition, at the time of performing control such that the display section displays the first state.
