The best one I've downloaded I like that it reads out the precise measurement, good job developers!
Not very good Maybe it's just my mobile but it seems to be only 5 cm long!! Too complicated. Some other apps are way easier to use. :-[
Could be better I could not calibrate the scale. Next to a "real" ruler, the app was off by 1mm. Also could use auto off to conserve battery.
Ruler is inaccurate Ruler is about 6 percent long; can't seem to calibrate
Looks very nice I am having trouble with measuring, I can be at 2.5 inches and it will show .786 inches , and I just used a random number.
Internal library fixed
