A free app for Android, by ПроВокруг.

The ProVokrug AR app is a tool for gain experience about the spatial solutions of apartments in serial Soviet and Russian buildings.

In the AR (augmented reality) mode, the app shows you an image of the selected building and its apartments. The image can be viewed on your smartphone or tablet.

You can explore the 3D model of the building to see how people lived and live in such houses.

You can customize the view by enabling or disabling walls, furnishings, floors, and other elements.

If you have a compatible device, you can use the ProVokrug AR app to view the 3D model of your building.
