Abstract: A machine may be configured to perform A/B testing on mobile applications. For example, the machine receives an identifier. The machine identifies a particular experiment variant for a mobile application based on the identifier. The machine generates an instruction executable by the mobile application to cause a display of a user interface on a mobile device according to a user interface layout based on the particular experiment variant. The machine, in response to the receiving of the identifier of the mobile device, transmits the instruction to the mobile device. An execution of the instruction on the mobile device results in the display of the user interface on the mobile device according to the user interface layout based on the particular experiment variant. The machine generates metric data associated with the particular experiment data based on tracking one or more interactions with the user interface on the mobile device.

Abstract: A system to effectuate passive check-in with respect to a user's mobile device is described. A server system may be configured to receive communications from a GPS-enabled mobile device (e.g., a mobile phone), extract a stream of locations from the received communications, and use the location information to determine whether a boundary-crossing event has occurred with respect to the mobile device. In response to detecting a boundary-crossing event, the server may communicate a message, such as a recommendation, to the mobile device.

Abstract: A machine may be configured to perform A/B testing on mobile applications. For example, the machine receives an identifier of a mobile device that stores a mobile application. The machine identifies a parameter of an element of a user interface displayed by the mobile application on the mobile device. The identifying of the parameter may be based on the identifier of the mobile device. The machine selects a parameter value that corresponds to the parameter. The selecting of the parameter value may be based on the identifier of the mobile device. The machine generates an instruction referencing the parameter value. The instruction may be executable by the mobile application to display the element of the user interface on the mobile device according to the parameter value. The machine transmits the instruction to the mobile device in response to receiving the identifier of the mobile device.

Abstract: Techniques for electing winning treatments in connection with A/B testing of mobile applications are described. According to various embodiments, the activation of a version of a mobile application installed on a mobile device may be detected. A database storing winning treatment information describing one or more winning treatments for one or more A/B tests is accessed. In some embodiments, each of the one or more A/B tests in the winning treatment information may be associated with a particular version of a particular mobile application. Thereafter, a specific winning treatment for a specific A/B test associated with the version of the mobile application installed on the mobile device may be determined, based on the winning treatment information. The specific winning treatment may then be implemented in the mobile application installed on the mobile device.
