ProTrac is a new style of Protractor.
Lay the device flat on a surface and draw lines at different angles alongside your iPhone or iPad.
Or use the side of your iPhone or iPad to measure the angle between two lines.
ProTrac uses attitude to keep track of the yaw angle which then rotates an image of a protractor.
