Pace Chart is an iOS application that is used to calculate mile paces for runners. To calculate the necessary mile pace for a race, first drag the distance slider to the desired distance.  Next, specify a race time by dragging the hours, minutes and seconds sliders to the appropriate values. 

To switch the race distance from kilometers to miles and back just double-tap the word distance on the screen.  To change between 1600m times and mile times double tap the word Time near the mile/1600m pace.  

When a race time is specified the corresponding mile/1600m time is immediately returned and vice versa. 

Tip: To zero out any time dial simply double-tap the corresponding label.
