An inhaler device including an atomizer configured to consume a first accumulated capacity and a second accumulated capacity to generate aerosol, and a light emitting diode (LED) configured to output a notification to an inhaler of the aerosol. The inhaler device further including circuitry configured to cause the LED to function in a first mode when the first accumulated capacity, detected or estimated, is smaller than a first threshold and the second accumulated capacity, detected or estimated, is equal to or larger than a second threshold, and cause the LED to function in a second mode different from the first mode when the first accumulated capacity is smaller than the first threshold and the second accumulated capacity is smaller than the second threshold.
