The electronic device 10 realizes a physical unit specified by the user, and a measuring unit 113 that measures the amount of activity of the user according to a signal indicating the amount of exercise output from the sensor 17 that detects the physical movement of the user. The required activity amount acquisition unit 115 that acquires the required activity amount calculated according to a predetermined calculation formula according to the index value of the designated physical characteristic as the activity amount to perform, and the measurement unit 113 during the first measurement period With respect to the target activity amount determined by adding the reference activity amount calculated based on the measured activity amount to the required activity amount, the measurement activity amount measured by the measurement unit 113 in the second measurement period after the first measurement period. The determination result acquisition part 116 which acquires the determination result of the target achievement level achieved is provided.電子装置１０は、利用者の身体運動を検出するセンサ１７から出力される運動量を示す信号に応じて利用者の活動量を測定する測定部１１３と、利用者により指定される身体的特性を実現するための活動量として、指定される身体的特性の指標値に応じて所定の算出式に従って算出される所要活動量を取得する所要活動量取得部１１５と、測定部１１３が第１測定期間に測定した活動量に基づき算出される基準活動量を所要活動量に加味して決定される目標活動量に対し、第１測定期間以後の第２測定期間において測定部１１３が測定する測定活動量により達成される目標達成度の判定結果を取得する判定結果取得部１１６を、備える。
