Very nice!

I used a plumb bob attached to the bottom of my phone set at 5 foot, and adjusted the height setting to 5 foot. I then laid a tape measure at 20 foot. The distance read 21 feet, but my ceiling read 8.3(very close) Im hoping with some tweaking I can get it a little more accurate. I am planning on using the app to make cubic foot measurements of inside rooms. The measurements do not need to be very accurate, so it probably will work fine.
