For the serious autocrosser who wants to keep track of their times, PAXitis is the solution.
PAXitis allows you to easily enter times and penalties and will calculate the resulting PAX/RTP time -- or the real time -- based upon the current class names and values. PAXitis will also compare times that you've entered to show the position and real time behind first place. Rotate the iPhone or iPod Touch to landscape mode, and PAXitis will also display the driver raw time and best scratch time.
In addition, PAXitis supports time entry in either portrait or landscape modes, to make it easier and quicker to enter times and penalties accurately.
