My Teen-Aged Son, Max,  Routinely Bit His Thumb Knuckle To The Point Where He Broke The Skin And It Callused. He Wished He Didn’t Do This, But Found It Difficult  To Quit. 


This Behavior Mostly Occurred When He Was Doing Homework, Working On His Computer Or Engaged In Similar Activities; He Was Not Even Aware He Was Doing It. He Believed He Could Stop Biting His Knuckle If He Was More Cognizant Of When He Was Doing It.  As A Concerned Parent, I Would Tell Max To “Stop It” When I Saw Him Engaged In The Behavior.  He Appreciated My Reminder.  It Was Very Helpful, But Of Course, I Couldn’t Always Be Around To Remind Him. I Thought, If Only There Was A Way He Could Be Automatically Reminded When He Was Biting His Knuckle--Thus The Genesis Of Stopbit.  Stopbit Uses Motion Sensing Technology Housed In A Fitness Tracker-Like Wristband That Offers A Gentle Vibration When The Hand  Is Raised To The Head And Face.. Now, Whenever Max Moves His Hand To His Mouth, He Feels  A Vibration Which Reminds Him To Stop Biting.  I Don’t Have To Be With Him To Say, “Stop It!”  It Is Simple Behavior Modification.


After Extensive Research We Learned That Millions Of People Also Engage In  Body-Focused Repetitive Behaviors Involving The Face And Head.   Our Solution That Helped Max Stop Biting His Knuckle Would Help Others  Who Bite Their Nails, Pull Their Hair Or Pick At Their Skin On Or Around Their Face. 


We Hope Stopbit  Helps You Or The Ones You Love The Way It Helped Max.  These Behaviors Can Be Embarrassing And Sometimes Cause Physical Harm. You Don’t Have To Live With Them. Being Aware That You Are Engaged In The Behavior And Be Given A Discrete Reminder To Stop Can Be The Solution You Have Been Seeking. We Hope You’ll Give Stopbit  A Try And Tell Us About Your Story.
