I am looking to have an iphone application designed for use as a tape measure function. The basic idea is to determine the length of something on the fly. My basic idea of function is that you would find the item to measure for example a desk, you click a button to start the measurement, drag the iphone across the distance of the object then click the button again to stop the measurement. the length of the item would then be given. Please let me know if any additional info would be needed.
