If this has been addressed elsewhere, I apologize. I looked but couldn't find it.
I'm looking for an app for my Android tablet that will allow me to use a wire to tether my D810 to it and be able to scroll through the photos and, ideally, rate them. I don't care about image stacking or controlling my camera or anything else. I just want to be able to do portraits and review them with the subject. Free is good. ;-)
