Loved the sweep mode. The only app that work in play store. Results depend on calibration and height. Best works. Flat surface.

Literally every mode was inaccurate and also, I didn't think this was possible for a ruler app but was confusing as well!(?) HTC Droid incredible

Cool idea but doesn't work & eats battery slide function really cool idea, but not repeatable accurate. MORE CONCERNING is that it is running in background when I never opened it.
