user15714: I'm looking for an android app for a variant of chess which is called Kriegspiel. (https://en.wikipedia.org/wiki/Kriegspiel_(chess))
I don't expect any PvP app but I'd satisfied with PvC app. (OK; I know it's harder to make PvC) 
And if somebody knows fairly good computer software for Kriegspiel please recommend it to me. I know one software, http://www.kriegspiel.co.uk/ but just in case if there is a better software.

user15365: There is an app called Dark Chess:
Dark Chess for Android
I know it's not exactly the variation you asked for, but I thought it could be useful in some way.
