Keen is a smart bracelet 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 is trained with a companion mobile app one time by performing your specific gesture for 20 seconds.  Nail biters would train Keen by actually biting their nails. Hair pullers who play with a patch of hair before pulling would train Keen by playing with their hair.  Keen's sophisticated motion sensors record the "fingerprint" of your repetitive behavior, and thereafter silently monitor your hand.  When Keen senses your gesture, it makes you aware with a gentle vibration.

The Keen is used in connection with a smart device, most often either an Android phone or iOS phone. It can also work an iPad etc.   You will download the app and connect it to the Keen through Bluetooth.  Using the in-app instructions, you then train it to recognize the gesture you are wanting it to "see".  Once you have trained it, when your hand moves to that area, the Keen will vibrate to let you know you can move your hand away without performing the gesture (be it hair pulling, skin picking, nail-biting etc.) as these are often subconscious behaviors and without Keen's vibration to remind you, you do not realize it is happening. The training involves performing the behavior for the Keen to "see" so it knows what to look for in the future. 

Once the vibration is received, you push the button to record the event (if you want the data).  You can train up to 4 areas, and there are step-by-step instructions on the setup and training in the app, as well as help from this support desk at and pre-recorded videos, blogs, etc. on our site.
