I don't know about an app but you can download photos into your own Houzz Ideabook and make sketches with your room photos and add on-line decor into the sketch- at least that's what I can do on my laptop.

I am pleased with the quality of work they do at https://yousee.studio/ for apartment and home designs. They provided me with several design options and I chose the one that best suited my needs. Their 3D images were very convincing and I couldn't believe how realistic everything looked. They were professional and friendly in their communication, and I was very happy with the result.
