an iOS app to help keep points during a scrabble game?

Hello to all. does anyone know of a good preferably free iOS app to help keep scrabble points? I just got a scrabble game for christmas and I want a way to keep track of my points and the other person's points with out adding all the letters together as I'm still learning how the board is read. It's a braille board if that helps. Anyway all happy holidays. and thanks.
