Abstract: A To-Do management apparatus includes a memory and a processor including hardware. The processor is configured to detect a time in which a driver of a vehicle is freed from driving operations of the vehicle, and provide, in the detected time, the driver with information for promoting accomplishment of a work that is entered in advance, that is not related to the driving operations of the vehicle, and that needs to be executed by the driver. Thus, it is possible to promote the accomplishment of the work that needs to be executed by the driver, at an appropriate timing and without interfering with the driver's driving operations.

Abstract: A circuitry estimates a degree of interest in each of destination candidates for each of subject users included in a user group determined based on degree of affinity among multiple users. The circuitry sets a location in which the degree of interest of a first one of the subject users is greater than or equal to a predetermined degree-of-interest threshold value as a first destination. The circuitry provides a second one of the subject users with a first trip proposal when the degree of interest of the second user in the first destination is greater than or equal to the predetermined degree-of-interest threshold value. The circuitry provides the second user with a second trip proposal when the degree of interest of the second user in the first destination is less than the predetermined degree-of-interest threshold value.
