Bughouse Chess Simulator app for iPhone and iPad

A simulator for bughouse chess: a fun and exciting team variant of chess.
Bughouse is a 2v2 game with 2 chess boards.
One team member plays with the white pieces on one board, and his teammate plays with the black pieces on the other board.
When a player captures a piece, it is passed to his teammate, who can then drop it wherever he wants on the board instead of a normal chess move.
The only limitation is that pawns cannot be placed on the last rank, where they promote.

Bughouse chess is usually played with a blitz time control, to prevent players from delaying their turn until they receive the piece they need.
The app supports multiple time control settings.
It also supports another variant of bughouse, in which checkmating the opponent by dropping a piece is not allowed - making for a more intricate and challenging game.
