Wast of time This app is to make people fool, they have made this application look good from outside but from the inside it suck the ruler in the app is the most funny part u can change the scale to any scale u want let me ask the person who made this idiotic app if the scale of the ruler is changed then how the hell will the measurement be same, Coze when I changed the scale 1cm had become 3.5cm and I did not try scaling it more. The same is the problem with the rest of the app links
Useful Unsure of the accuracy of some of the tools, but it's a good pile of tools regardless.
Fair play. ... not bad at all
Very good App
