Abstract: An electronic device for communicating with a wearable device applying an external force to a user. The electronic device may include a communication module configured to establish a wireless communication link with the wearable device, a display, a memory configured to store a fitness application, and a processor configured to execute the fitness application and control the display so that a screen of the executed fitness application including a first area is displayed on the display. The processor may be configured to receive first state information indicating that the wearable device is in a sensing state for sensing a motion of the user through the communication module, recognize a state of the wearable device as the sensing state according to the received first state information, and control the display to provide visual feedback corresponding to the sensing state through the first area.

Abstract: An electronic device and/or a wearable device providing exercise amount measurement information, and/or operation methods thereof. An electronic device may include: a communication module configured to receive, from a wearable device, sensor data including movement information during an exercise of a user wearing the wearable device; an input module configured to receive a user input that selects an exercise intensity to be applied to the exercise of the user; a processor configured to estimate an exercise amount of the user based on the received sensor data and the selected exercise intensity, and generate an exercise activity indicator including at least one graphic indicator indicating the estimated exercise amount; and a display module configured to output a graphical user interface (GUI) on which the exercise activity indicator is displayed.
