Ratings and reviews

Works as good as I need it to! Checked with a caliper, the initial generic calibration was actually within about 0.2% of being correct (was set initially upon app startup at 4.07"). A clear ruler that can fit flat on your screen would work well for your calibration. Remember, calibrate at the largest size measurement device you can accurately align with on the screen. While app can calibrate with a coin, calibration will have less error at I.E., 5.00" vs 0.75".

I used an 8mm earring for measurement and it's really accurate. Even with default calibration it shows what it has to show. With the size of a credit card for calibration it comes as a handy tool too if the default falls short, so it's a well done indeed. So now I can at least have an idea when I online shop how big an object is.

What a super little app for positioning tables, diagrams, pictures, etc in documents, pdfs. Best using it as a pop-up app overlaying say an Adobe document, as it can be faded (made see through), and it is easy to go back and forth. Just brilliant. And feedback!
