Brick is gray square, approximately 2 by 2 inches, that pairs with a user’s phone. Users can choose which apps they want to block and which ones they want to keep running, and then tap the Brick to lock the apps they’ve selected. In order to unblock the application, users have to tap the Brick again. The idea is that you would keep your Brick in a separate location from your phone most of the time, thereby making access to all of your locked apps much less convenient.
