Abstract: Computer-implemented methods, computer-readable storage media storing instructions and computer systems for labeling significant locations based on contextual data can be implemented to perform operations that include determining a location of a computing device, and determining a label for the determined location based on contextual data associated with the significant location. The location can be a significant location that has meaning to a user of the device.

Abstract: Systems, methods, and program products for determining a location of a mobile device using a location application programming interface (API) are described. A mobile device can receive an input requesting the mobile device to monitor entry into and exit from a significant location. The mobile device can call a start-monitoring instance function of an object of a location manager class as declared in the API to start monitoring, and call a stop-monitoring instance function of the object as declared in the API to stop monitoring. The mobile device can store the entry and exit, or provide a record of the entry or exit to a function that is conformant to the API for performing various tasks.
