Tile counter

I just purchased this game because I love to play scrabble. I wanted the no ads version and am very happy with it. Still learning my way around the board and where everything is.
One thing I notice is missing and that is the box that tells you how many tiles are left in the game..
My friends and I have been playing Words with Friends 2. It has that feature but the ads are horrific to deal with.
You would make this game complete if you added that feature to this paid version.
5 stars with the tiles left box.
One more question. Can this app be installed on an iPhone? Thamks
