Mini4WD is a car lap timer app, which allows you to measure the lap time of a car or bike, easily and accurately. It provides a visual display of the lap time, and saves the results in a log book for future reference. It also provides a warning message, which can be disabled in the settings, to remind you of the upcoming lap.
