Jogularity is a rally timing system developed by English rallymaster John Brown. In the U.S., this style of rallying is often called Regularity and is common in historic car rallies where accurate distance measurement is secondary to maintaining prescribed average speeds.

In a Jogularity event you will be issued route instructions and a set of elapsed times to specific points on the course as well as the cumulative time for the entire route. Your job is to maintain an average speed to reach the various timed points with zero timing error. Along the way there will be control points where your progress will be measured, so try to match the average speed as closely as you can between timed points.

When you reach timed points, record the split time by touching the clock face. The current split time and the cumulative time will be logged in a table and compare these times with those indicated on the route instructions to see how well you are maintaining the ideal pace.

To clear the list of split times, touch the "Clear Log" button and answer the question "Yes." Start the rally by touching the clock face or by waiting until the next full minute.

On the clock face, time can be measured in either seconds or decimal minutes. Additionally, there are two levels of time precision. One displays two digits for seconds or two digits for hundredths of a minute. For more precision, there are other measures of seconds as two digits plus tenths of a second or three digits for thousandths of a minute.

There are three clock face styles: black, yellow, and white.
