NOTE
This is a legacy version of the scrabble clock that supports older devices running Android 1.6 or later.
There is a newer version of the clock ("Chess Clock for Scrabble") targeting Android 4.2 and later. The new clock includes a light theme and the airplane mode feature has been removed in order to require less permissions.
