BearChess is an independent chess GUI for UCI engines with direct support for electronic chessboards (Certabo, TabuTronic Cerno/SentioiChessOneMillennium ChessLink and eOne,  DGT (e-Board and Pegasus), Chessnut Air/Pro, Square Off Pro, NOVAG Citrine/UCB, Saitek OSA).

Why yet another chess GUI?

Many GUIs support electronic chessboards, but do not use the full potential that chessboards with piece recognition offer. They could be much better used for training or analysis of games and positions.

So the focus of BearChess is more on exploiting the possibilities of the chessboards than being just another GUI. Look at the video tutorials for more details.
