[Description] Stopwatch that can measure up to nanoseconds. However, the reaction of the people is not accurate to nanoseconds. So it might make sense can be measured up to nano-seconds, but I tried to create. Accuracy will decrease by the processing capacity of the terminal. If you change the format option, you can use it as an ordinary stopwatch in milliseconds. You can change the font size option. You can measure lap and split. [How to use] 1.Press the start button. 2.Press the lap button. 3.Measurement is finished, Stop button. 4.Again, press the start button, the measurement is restarted. [Option] Adjust font size of the timer.
