Implementations herein include receiving a first signal from a first mobile computing device, the first signal indicative of a first state change and receiving a second signal from a second mobile computing device, the second signal indicative of a second state change. The method may also include determining that the first state change and the second state change are related, and that the first mobile computing device and the second mobile computing device are currently located at a common geographic location. The method may further include determining that a third mobile computing device is currently located at the common geographic location. The method may also include transmitting to the third mobile computing device, a third signal indicative of a recommended state change, the recommended state change being based on the first state change at the first mobile computing device and the second state change at the second mobile computing device.
