Electronic devices can facilitate collective and accurate scorekeeping. A first electronic mobile device can communicate (directly or indirectly) with a second electronic mobile device. Respective users can use the devices to identify when and/or how a score is to be adjusted. The input can be processed at a mobile device or central server to determine whether and/or how to adjust a score. Score adjustment can depend on whether any other input includes inconsistent information. The score adjustments can be pushed to one or more mobile devices. In this manner, all mobile devices can display a consistent and current score.
