Wattblock is a free Android application developed by What The Appz for Watter players. It is a tool that helps players keep track of their points without the need for paper and pen. The app assigns points with a simple finger flick, and if a team is deleted, the app automatically updates the score.

One of the most convenient features of Wattblock is its ability to function even in semi-darkness. Players can also request to keep the backlight on to avoid the hassle of constantly restarting the app.

Note that this is not a game but a tool designed solely for keeping track of points in Watter. The idea behind the app comes from Angelika Tausch, while the design is by Kathrin Obletter.
