I got this (full) app, and puzzle 119 of the "Mate in 3" series appears to be broken; it will not accept the second move in the sequence. Trying the "Hint" feature at this point gives the target square and the piece-to-move square in the opposite order, which I presume is part of the fault.
(Of course I'm guessing at Black's second move; I've put in ...Qxb6 Qxb6#; it could just as easily be ...Qc7 Qxc7#; I don't know which you intended)
