I’m very new to augmented reality, does anyone know if there’s an app- or any sort of program you could use to upload a 3d model to, and view it on an IPhone from a computer?

I’m specifically looking for a way to make a 3D model in a program like Blender, then be able to visualize it through my IPhone in AR.

If there isn’t anything like that, then why? is it especially hard to make a system like that because of how AR tries to place a model on the screen?

And if it wasn’t that hard it just doesn’t exist yet, how hard would it be to develop an application like that?
