Didn’t know how effective calibration would be!


I didn’t realize how much of an improvement this app would make for my structure sensor apps. I don’t know what it does but it’s really effective.

Simple and effective


The calibration app makes it very easy to match the structure sensor camera to the iPad camera. The end result is much better 3D scans when adding color.

Can't calibrate


I bought this back in 2015 and put it away for a couple year due to family events and I come back and they want proof of purchase from 3 years ago to "Allow" me to use their software again even though before I used it without issue and without neighbor held hostage. If your looking for scanners look elsewhere
