I choose to review the app Augment 3D. It is to browse 3d models. Also to add and share your own models. The viewing is suppose to be in real time and actual size. When opening the app you can explore the public gallery. It also says you can login to an account. But doesn’t offer signup. And it has a QR scanner but I’m not sure about its specific use. It has 7 categories : Architecture/Home(doesn’t work)/Kitchen Planner/Cultural Heritage /Electronics/ Made by Augment.
