Abstract: In one embodiment, a non-transitory processor-readable medium stores code representing instructions that when executed cause a processor to receive a first signal including a performance datum associated with a first mobile application resident at a mobile device. The code can further represent instructions that when executed cause the processor to receive a second signal including a performance datum associated with a second mobile application resident at the mobile device. The code can further represent instructions that when executed cause the processor to send, based on the first signal and the second signal, a third signal including at least one performance metric based at least in part on the performance datum associated with the first mobile application and the performance datum associated with the second mobile application.

Abstract: A method of supporting portable digital devices includes providing each device with an installed service application. The service application for each device monitors operational parameters associated with other applications that are running on the device. When a monitored parameter suggests a device operational problem, the service application generates an alert, and it provides the device's user with information about how to resolve the alert. The application also may transmit the alert, along with data showing the applications running and the monitored parameters at the time of the alert, to a remote service operation. Also, during non-alert conditions, the application may periodically transmit data showing the applications running and the monitored parameters at the time of the transmission. The service operation may use this data to identify trends, manage device operation, or perform other functions.
