An example of an information processing system includes a stationary type device, a hand-held type device, and a server. The stationary type device senses user information for evaluating health of a user. The hand-held type device transmits the user information sensed by the stationary type device and/or information calculated from the user information to the server as transmission information. The server transmits, to the hand-held type device, service data for providing the user with a network service in accordance with an evaluation result of health, indicated by the transmission information transmitted from the hand-held type device and/or calculated from the transmission information.
