"blindfold" smartphone chess app?

Anyone know of a "blindfold" chess app for a smartphone that takes its input from an interface that is NOT an 8x8 chessboard - so, either verbally through Siri or from some other screen layout?

(In other words, this app requires its human opponent to visualize the board without assistance.)

Cool idea. Like something with a "command line" mode or voice interface as you say... But sorry, I'm into iOS & the only app I know of with any blindfold mode is tChess Pro (in which you see & move via the board).

why not makes moves in notation and just glimpse the board as an option, but with only the last move written and visible. so the board is hidden and the moves list is hidden unless the user clicks to reveal either of them
