VisualRuler 2.0

Simple and Very useful...accuracy is appropriate for how easy it is to use. Nice work.

It always shows the exact same size, no matter how really big is the object

Should be more useful if the app can automatically locate the card and attach the box(the given one).

Although it is not working perfectly at the moment, I am giving it 5 stars for the innovative idea and hoping for the updates for improvement!

The app doesn't make the 2nd rectangle to measure the 2nd item. It doesn't really detect the card as well. Very confusing. Good thing I got this for free.

Useful

Not easy to use, very complicated

I measured a 26cm ruler with this app, and it told me it is 20cm long. A second test on a small 2.7cm square object and it read 2.1cm. Worthless.

Apparently my TV is the same size as my Apple Remote and a thimble.

It took many tries to figure out how to use this. Once you realize you need to push the plus sign to measure something, whether it's a box or line, after you've encircled the CC, it will work. If you are not directly over the object to be measured when taking the photo, boxes won't measure accurately. If you need a measurement without having a tape measure or ruler, it can be a great help, but I'd try to be on wifi if you could.
