Excellent application with scientific value

I really liked the radar mode. It works exactly like radar except with sound instead of microwaves--just like bats find their way around. I am also amazed at the accuracy in calculating the distance of all reflexions. I put my hand in front, and it detected my hand, the monitor, and wall behind it. I moved my hand half and inch, and it detected the change.
However, this is not a replacement for a contractor tool, as the iPhones microphone is not directional. But is still useful to give a rough idea of a rooms dimentions (like when shopping for a home).
My wife did complain about the high pitch sound (over 7khz, which I cannot hear). So this tool can also be used to keep teenagers away. :-)
