Clockulator

Clockulator is a clock calculator designed for use by coaches, athletes, scientists, and anyone who has to do simple addition, subtraction, multiplication, and division on time values. There are a large number of uses for a time calculator: Adding up 4 individual splits to get the total relay time. Or adding up 3 splits and subtract from the target time to calculate what the fourth split needs to be. Or converting yard times to meter times by multiplying by 1.1. Or calculating your mile pace by dividing your 5K time by 3.1. Or adding a column of times from repetitions of a workout or an experiment to get the total time, and then divide to get the average time.

Clockulator also includes a memory function to easily repeat the usage of any value, and a unique history function that allows the user to review previous calculations in a familiar arithmetic format.
