Abstract: In one implementation, a computer-implemented method includes detecting, by a mobile computing device, a current context associated with the mobile computing device, the current context being external to the mobile computing device and indicating a current state of the mobile computing device in its surrounding environment. The method can also include identifying, based on at least a first portion of the current context, a location description for the mobile computing device, wherein the location description includes a textual description of the location; and determining, based on the identified location description and at least a second portion of the current context, whether to switch the mobile computing device from operating using a current profile to operating using a second profile, wherein the current profile and the second profile each define one or more settings of the mobile computing device.

Abstract: The subject matter of this specification can be embodied in, among other things, a method that includes receiving an electronic voting request from an originating mobile device at a recipient mobile device. Each mobile device is associated with a member of a voting group. The electronic voting request includes a voting ballot and instructions, that when executed by a processor, perform operations including generating a vote based on information in the voting ballot and transmitting the voting request to at least a portion of other members of the voting group that have not received the voting request. The operations also include receiving votes from the portion of the other members to which the voting request was transmitted and transmitting a tally of the received votes to the originating mobile device.
