Letterteller, which means 'Tile Counter' in some weird language, is a very simple but powerful app for the Wordfeud fanatic. It shows you how many of each letter are still in the game. That is: the tiles that are neither on the board nor on your rack. In order to login to the Wordfeud server you have to provide the email adress and password that you use in the Wordfeud app.
The download of the app is safe and secure. Eippod Apps is the official developer of Tile Counter that can be found in the Word Games category. The game has been downloaded and set up by over 0,5K users and the most recent update was released on Jun 22, 2014.
