Can you provide feedback on my new iPhone app, PLEASE?

I just launched a new iPhone app and I would really like some feedback. It is a 3D app that allows you to combine 3D Models with pictures taken on your iPhone. For example, test which couch looks best in your living room before you buy it.

It’s free and very easy to use? Try it and let me know…would you use this?
