Reco on Android DOF calculator for D800? And Coc vallue?

In this thread in the attempt to better understand my soft focus problem with D800, Per Baekgaard brought up a good point that CoC of D800 is different than typical camera.

This article by George Douvos has a good calculation and defined CoC for D800 should be 10 microns.  Do you agree that this is the right value?

"The Nikon D800 is blessed with a 35.9 x 24 mm, 7360 x 4912 pixel sensor. It thus packs 7360 pixels into 35.9 mm (and 4912 pixels into 24 mm). That makes 205 pixels per mm. And that makes each pixel about 5 microns in size.

At best, the smallest detail that a sensor can resolve spans the width of at least two pixels. So the D800 should be able to resolve image detail as small as 10 microns or so.*"

Also, the article pointed to an Iphone app TrueDoF-Pro

that allow users to input their custom CoC value.  Do you have any reco for similiar Android app?
