Examples of the present disclosure also provide a contact matching apparatus. The solution of the present disclosure improves contact matching efficiency and accuracy.

Abstract: In one embodiment, a mobile-client system may receive user input from a first user to send a message to a plurality of second users. The user input may include an indication of the first user currently being located at a first geographic location, a time period for which the first geographic location of the first user is visible to the plurality of second users, and one or more content items shared by the first user. The mobile-client system may send the message to one or more second users selected from the plurality of second users. The mobile-client system may receive a notification referencing one or more of the selected second users to whom the message was sent. The notification may include an indication of one or more second geographic locations shared by the one or more of the selected second users.

Abstract: In one embodiment, a mobile-client system may store location history data during a first time period in its memory, where the location history data comprises a plurality of geographic locations during the first time period and one or more time stamps corresponding to each of the geographic locations.
