Keen is designed to help you become aware of subconscious behaviors that are physical, repetitive movements or gestures of the hands, focused on the body. These behaviors are often called Body Focused Repetitive Behaviors, or BFRBs. They include, but are not limited to: hair pulling (trichotillomania), nail biting (onychophagia), skin picking (dermatillomania / excoriation disorder), and thumb sucking.
Keen generally works best with behaviors related to hand gestures near the head, face, and legs. We have also had some customers successfully use Keen for picking of the hands and arms, though a user may find greater false alarms with these areas of the body. If you are unsure if Keen can be used for your behavior, send us a note at email@example.com.
