Do You Use An "in Situ" App?

Hi all. Wondering if anyone has experience to share on using an "in situ" app or website? This is a method of showing your artwork in an interior setting, a virtual display. "Shoot and Sell" looks good but comes at a cost, and is only available on tablets. I normally use my desktop and phone, so I'd have to use my 11 year old son's tablet and I'd have to set up Dropbox to access my images.
Is there another solution? Thoughts?
