Location-based methods, systems, and program products for performing an action at a user device

Methods, program products, and systems for location-based reminders are disclosed. A first user device can receive an input specifying that a reminder be presented at a given location. The first user device can provide a reminder request, including type and content of the reminder and the location, to a server computer for pushing to one or more user devices. A second user device, upon receiving the reminder request, can determine a device location of the second user device. If the given location matches the device location, the second user device can present the reminder in a user interface. 本公开涉及基于位置在用户设备处执行动作的方法、系统和程序产品。第用户设备可以接收规定在给定位置呈现提醒的输入。该第用户设备可以向服务器计算机提供包括提醒的类型和内容以及位置的提醒请求，用于推送至个或多个用户设备。第二用户设备接收到该提醒请求后可以确定该第二用户设备的设备位置。如果所述给定位置与该设备位置相匹配，则第二用户设备可以在用户界面内呈现所述提醒。
