@alina_karnaukh android is probably out of the question. This app uses apple's proprietary ARkit platform introduced in iOS 11

@thierry_g going to assume you'll need to start the measurement by touching the camera to the object so it always starts at 0 distance

@sasha_lah Well, I'm not sure it explains how it could measure the distance between the object and the camera. Even by touching the object first, in the case of the picture frame measured in diagonal, I don't understand how it's possible. Imagine if the user move toward the wall, really close to it. Then between the top-left corner and the bottom-right corner, the phone would move on a really really short distance... How can the app handle that?

@sasha_lah @thierry_g Apple's ARKit (in iOS 11) provides this functionality. By using video and observing objects as they move in the camera view, ARKit can create a 3D mapping of the environment. Once it has enough reference points you can get the distance between points in the 3D.

@jorijn thanks! Yes, metric units will be included :)

@wilperkins I have ios11 anyway I can get it now?

@tadwook You linked to the edit link. I think this is the link you wanted:

@theashtube thanks for catching my mistake ; )

@jasondainter This is using Apple's proprietary ARKit which comes out in the fall to all users with ios11. Which means it will be the most compatible version to date, and it is one of the first fully functional apps created around this software.

@jasondainter I think the main difference is 'Measurement Tool' needs a size reference in the view in order to calculate the measurements. This uses an analysis of the real world to create a "map" of the environment and so knows where points are in 3D and can measure the distance between them. No reference object required.
