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

★★★

ruler is fine for up to about 3inches but ad lessens usable space, sweep mode depends on you moving a precise speed to get a fairly accurate result, distance works fairly well

Whether or not the I'm measuring on a flat horizontal surface out a vertical wall, the readings are always way off. Do not download this app
