An apparatus and method for notifying observation data to an application program which includes a memory which stores observation data received from a sensor and time information corresponding to the observation data are provided. The apparatus includes an evaluation-data calculating unit which calculates amount-of-change evaluation data based on the received newest observation data and former observation data notified to the application program, a determination unit which determines whether the amount-of-change evaluation data is greater than or equal to reference change amount, and a notification unit which notifies the observation data received from the sensor to the application program when the determination unit determines that the amount-of-change evaluation data is greater than or equal to the reference change amount.
