Let's Measure on the Go!

'Measure' is a phone app that allows you to have a measuring tape in your pocket!
The AR (augmented reality) app works using your camera to measure things
 around you.
Once you open the app it asks that you move the camera around to analyze
the object and measurement area. In doing so white dots appear over the
intended area, typically the camera picks up and catches the corners when
 you get near it and allows for adjustments.
Once the dots are placed a tap of the 'measure' button and a measurement
for the segment is given.
Of course there's no way to be 100% accurate so a margin of error is given.
If an error is made there is a clear button to start over for endless measurements.
