A wearable computing device comprises one or more motion sensors, a first circuit, and a second circuit. The one or more motion sensors are configured to measure swing motion. The first circuit is in communication with the one or more motion sensors and configured to translate measurements of the swing motion to machine-readable motion data and identify from the machine-readable motion data a golf shot in which a golf club held by a golfer contacts a golf ball. The second circuit is configured to increment a golf score of the golfer responsive to the golf shot being identified.
