Click a question for the answer:

1. Why did you make the Keen bracelet?

  • We made the Keen awareness bracelet out of a desire to solve co-founder Aneela's problem with compulsive hair pulling (trichotillomania). After seeing first-hand how helpful our first prototypes were for Aneela, and how profound her success was, we knew we could help others if we refined the solution. After much research, many conversations with doctors and consumers, and iterations of prototype after prototype, we brought Keen to the world.

2. What types of behaviors can Keen help me with?

  • Keen is designed to help you become aware of unwanted behaviors that are physical movements of the hands, repetitive and focused on the body. These 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 motions near the head, face, and legs. We have also had some customers successfully use it 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, just send us a note at hello@habitaware.com.

3. Who is Keen for? What ages? Is Keen for kids?

  • Keen is designed for kids (ages 8+) and adults who are ready to change.  If you bring the willingness, Keen provides the awareness.  With these two key ingredients you have the power to take control of your subconscious Body Focused Repetitive Behavior (BFRB).  Keen is not a magic wand that will stop your BFRB, but it is an instrumental tool in the process toward sustainable behavior change.  Keen provides the awareness, allowing you the choice to stop.  We encourage parents to talk with their kids to ensure they are ready for change before ordering.

4. Does Keen prevent me from doing my subconscious & unwanted behavior?

  • No, Keen cannot stop you and does not prevent the unwanted behavior from happening. It brings you awareness of where your hands are so that you can choose healthier alternatives. Once you have committed to changing your behavior, Keen can be a powerful tool that helps you succeed for the long-term.

5. What evidence do you have that this type of awareness bracelet works?

  • In addition to witnessing Aneela's success, we have researched the power of awareness thoroughly. While Keen represents a new technology, the idea for this type of bracelet in academic research is not new. Awareness underpins the current gold standard technique in behavior change, Cognitive Behavioral Therapy, and our bracelet enables and increases that awareness. Researchers at the University of Michigan have published a paper confirming awareness-enhancing devices work for behavior change. We are simply the first ones to make it a reality. Finally, we have expert advisors, Dr. Carol Novak and Dr. Varsha Reddy, who, after treating hundreds of patients with related behaviors, deeply believe in our solution.

6. How does Keen work? How is it specific to me?

  • After you take Keen out of the box, you train it with our app by performing your specific behavior for 15 seconds. For example, for nail biting, you train Keen by actually biting your nails. If you typically play with a patch of hair before pulling, you train Keen by playing with the hair. Keen's sophisticated motion sensors record the repetitive way you do the behavior, and thereafter silently monitors your hand. Once recorded, Keen simply makes you aware with a gentle vibration when you do the behavior.

7. Will Keen shock me?

  • No, Keen brings you into awareness with a simple vibration every time you perform your specific behavior. Expert psychologists confirm that there's a reason scientists stopped advocating for electric shock decades ago. The best way to change behavior sustainably and in a healthy way is through awareness and making a conscious positive choices.

8. Do I need two Keen smart bracelets?

  • Some people do certain behaviors with a dominant hand, and if you are one of them a single band will work fine.  If you use both your left and right hand to engage in the behavior you want to stop, then we recommend ordering a set of two Keen bands, one for each hand. This will help you retrain each hand away from the subconscious behavior. We offer a $30 discount off a set of two and multiple styles to ensure Keen blends in.

9. Can Keen learn multiple positions? Can I retrain Keen for a different behavior after I've trained it?

  • Yes, Keen can store up to 4 behaviors, and you can modify or delete these trained behaviors at any time. We highly recommend starting with training ONE behavior to get used to Keen and yourself - this is a journey to awareness, after all!

10. How do I train keen? Do I need a smart phone? What smart phones do you support?

  • For a complete guide to setting up Keen, please visit our Train Keen page.

    As for what phones we support, you will need to download our free Keen app and access it on one of the following smart devices:

    • iPhone 5 or later running iOS 9.3 or later

    • iPod Touch 5th gen or later running iOS 9.3 or later

    • iPad 4 or later running iOS 9.3 or later

    • Most recent Android models (2014 or later) supporting Bluetooth 4.0 and running KitKat (4.4) or later. NOTE that this list may change as we continue our quality and compatibility testing, but we have confirmed the following devices are compatible:

    • Google Nexus 6P, Google Nexus 5X

    • Samsung Galaxy S7 Edge, Samsung Galaxy S7, Samsung Galaxy S6 Edge Plus, Samsung Galaxy S6 Edge, Samsung Galaxy S6, Samsung Galaxy S5, Samsung Galaxy S4, Samsung Galaxy Note 5, Samsung Galaxy Note 4, Samsung Galaxy Note 3

    • HTC One M8 and HTC One M7

    • Moto X - models 2014 or later

    • We are adding more devices as we continue testing. If your device is not listed, please email us to double-check.

    After that, a constant Bluetooth connection is not required.  For example, a parent can help a child calibrate the Keen band with the parent's smartphone, but the child does not need to keep the smartphone near her.  When Keen and the smartphone come back in range of each other, you will be able to sync data from the bracelet to the Keen app to access the insights from the app.

11. How accurate is Keen?  I bite my nails - is Keen going to vibrate every time I drink a glass of water?  Can I snooze the Keen bracelet?

  • While false positives are impossible to eliminate completely, we have been working to reduce them! We have a sophisticated motion capture algorithm and will continue to refine it based on our user's feedback. In general, you may get some errant vibrations, but with most behaviors, it should not go off every time you raise your hand to your face to eat or drink.

    There are settings to adjust for the preference of the user.  For instance, you can select fewer reminders if you do the behavior in a specific way, or more if you want to be notified whenever the hand is in the danger area. Psychologists tell us that even unnecessary reminders for benign behavior help increase awareness of hand position, which is helpful for long-term behavior change. 

    Another feature to reduce false alarms is snooze. You can use this feature to pause detection for up to 30 minutes. To set the amount of time to snooze, use the Keen app. To initiate snooze, simply hold Keen's button for 2 vibrations (~3 seconds). You will feel a long vibration that confirms Keen's gesture detection is snoozed. To bring Keen out of snooze, simply hold the button for another 2 vibrations (~ 3 seconds). You will again feel a long vibration. More information is available here.

12. Can Keen help me while I drive?

  • The acceleration in a vehicle might throw the gesture detection off slightly. For most, it should work fine, and the settings can help fine-tune the detections. We can certainly tell you if your hand is raised near your head in a vehicle.

13. Can Keen help me while I sleep?

  • We have not tested Keen during sleep, and do not believe it will be helpful for most people in their sleep.  If you lie in the same position and do the behavior the same way, Keen will reliably give you vibration reminders.  If you change your sleeping position quite a bit, as many people do, Keen will not be able to reliably give you accurate vibration reminders.

14. What are my color options for the Keen bracelet?

  • We offer the Sporty version of HabitAware Keen in black, teal and white, with the module. 

    Silicon straps for the Sporty Keen are available for purchase in black, navy, pink, red, teal and white (no module included).

  • Please note: Stylish Keen has been discontinued.

15. What material is Keen made out of?

  • The Sporty strap is made of silicone and its pegs are made of aluminum. The screws that hold the main gray plastic Keen unit together are coated in nickel. And in our Sporty Keen, the screws are sunk in and the silicone strap covers up the screw holes, so there would not be any skin contact.

    The Stylish Keen uses a leather strap with a buckle made of steel and aluminum.

  • Please note: Stylish Keen has been discontinued.
