ABSTRACT:
A wearable device for automatically counting and timing the repetitions or laps during an athletic activity. The device preferably is worn either on the palm of the hand or the ball of the foot and comprises a raised, pressure-sensitive area which is depressed automatically through contact with a solid surface as part of the user's natural action in completing a lap or repetition. The device preferably also comprises a watertight case enclosing a microprocessor circuit which records and calculates various information for the user and displays this information on a liquid crystal display. Selecting means are provided on the case for selecting the information appearing on the display such as laps completed, total distance traveled, time to complete each lap, average lap time, average speed, total elapsed time, real time, and best lap time. An adjustable strap holds the device to the user's body.
