Pros and cons of Ruler Pad app for iPhone and iPad

Ruler Pad app good for

simple and awesome. it was free yesterday, today 99 cent. i got lucky yesterday
Does what it says - great in that you can place objects on iPad surface and adjust sliders to measure.
It works very well, but it would be better if you could messure 2D. By adding two more lines, it is possible to measure vertically too. So i give it a 4 star.

Some bad moments

The app allows for easy controls. A useful tool for for simple measurements. I would give 5 stars if the sliders were lower (so a larger object can be placed on the screen surface) and if it had a note/calculation capabilities.
It works as explained. It was a little too hard for my students (elementary) but great idea.
Great! I can measure the 2.5mm and 3mm screws that come out of my MacBook and easily tell the difference, also the 9mm vs 10 mm ones. A necessary function done here first that Ive found.
Its a ruler utility. If it does what I want when I want it, and does it well than its good. If youre civilized and using metric its good. But if youre using standard its commoner to say 5 and 13/16 inches than to say 5.8125 inches. I couldnt find a way to change the ruler from metric to standard. Even another, standard, ruler at the bottom would have solved this
Can you add in future versions of the ability to set the position of labels with a digital input?
Opens on 6 plus with iOS8 just fine, but does not display correct distances. Its "inch" is significantly larger than an actual inch.
