Tweak is a watch concept, born out of an analyzation of the term "complicated monotony", that helps its user to break bad habits or enforce good ones. It uses cutting-edge technology to sense the movements and signals given by the body, and using that information to communicate with the user and encourage good habits while discouraging bad ones.

The design is minimalistic, aided by curvilinear elements and gentle colors. The two main hues used throughout the design - green and red - represent good and bad habits respectively in the interface.
