Plug the USB cable into the Keen "brain" (module), and attach the other end to a power source, like your computer or an adapter for the wall. 

The LED light bar will blink while charging and is solid white when fully charged.


To help you differentiate if you have two bracelets, you can mark your module as Left or Right using a permanent marker.

Charge time:  3 hours

Battery life:  1-2 days, depending on use.  

Get in the habit of charging Keen every night!

4. Wear Keen


After charging, insert one blank peg and EITHER the L or R peg into the bracelet, depending on which hand you plan to wear Keen on.

These pegs will keep the bracelet fastened snugly and are also a helpful reminder if you are using two bracelets. Always wear each Keen on the same hand you trained it for (it won't work otherwise!).

Face the button towards your fingers.  Always wear Keen in the same orientation that you trained it (it won't work otherwise!).



Slide the peg side through the safety loop. Make sure your bracelet fits snugly to ensure accurate behavior detection.

5. Connect and TRAIN: The Key step!

Please watch this quick overview of the in-app training process, the key step in making Keen work for you.

Keen works best if you train it in the same location and body position you want it to work.  

Keen is designed for a repetitive motion at the localized area.  During training, feel around for hair or skin imperfections, or bite your nails for the full 15-20 seconds.  Keen will record this behavior and look for this motion continuously.

6. ADJUST KEEN:  How to Use Detection Settings

Motion Fingerprint™ is Keen's proprietary gesture detection algorithm. Because no two motions are exactly the same (just like our fingerprints!), Motion Fingerprint™ uses highly sophisticated sensor mathematics & machine learning to more closely match your true motion to the trained motion for better detection.

If you find Keen is vibrating too often or not enough, you can customize Keen by using the Detection Settings. Please watch the video showing how to adjust Keen's motion and position settings.

Motion Sensitivity

"Tighten" the motion setting to reduce false alarms from similar movements, like nail biting vs. eating and drinking. "Widen" if not detecting enough true gestures.

A tighter motion setting will look very specifically for the motion you performed at the area while training the bracelet.  A wider setting will just look for your bracelet to be in the general area.

Position Sensitivity

Increase the position setting to improve detections when you change body position, such as sitting at a desk vs. leaning back on a couch. Decrease to reduce false positives.

Similar to motion sensitivity, a lower position setting will look very specifically for the position you took when training the bracelet. Increasing the setting allows for more variation in the position when detecting.


We won't be able to eliminate all false alarms, but most people should be able to find an optimal balance. Even false alarms help you develop awareness of your hand position!



7. Tracking your Behavior: Push Button

Push Keen's button any time you perform your behavior, and the bracelet will give a short acknowledgment vibration confirming it has logged an event.  Visit the Me tab in the app to view your progress over time.  Multiple button presses in the same minute will only show up as one event. 

8. Snoozing your device:  Hold the Button for Two Vibrations

If you are getting false alarms, for example while eating, hold Keen's button for two vibrations (~3 seconds) and release.  You will feel an acknowledgment vibration letting you know Keen has been snoozed.  After it "wakes up", it will send you another acknowledgment vibration.  The default snooze time is 7 minutes and can be changed in your app.  You can also wake it up manually by holding the button for two vibrations and releasing.

9. Training Multiple Areas

 Keen allows you to train up to 4 areas. We suggest you start with one area and get comfortable with how Keen works before adding additional areas. You can manage the areas trained by hitting "Manage Band" in the app and selecting "Add an Area" or swiping left on a trained area to delete.


Keen does not have an off button. If Keen is sitting idle (detects no motion), it will go into low power mode to conserve battery life. To learn how to snooze Keen, click here.


Keen is helping you become aware of where your hands are. This awareness, plus a willingness to change, gives you the power to take control of the behavior. Once aware that you are doing the behavior, ask yourself:

> Where am I?

> What am I doing?

> How am I feeling?

This understanding helps you identify your triggers and choose the best replacement strategy for that moment. One example is built right into Keen: a Guided Breathing Exercise.  Hold Keen's button for 3 vibrations (~10 seconds), and release.  Keen's light will breathe in and out with you for one minute.  Some other examples you can choose to do on your own are:

If you notice you perform the behavior when bored:

> Go for a quick walk

> Drink some water

> Stretch

If you notice you perform the behavior when tired:

> Sleep!

If you notice you perform the behavior when stressed:

> Practice deep breathing

> Do jumping jacks

Experiment to find what you like!

12.  HELP!  My Keen is not working!

Hard Reset:  If Keen is not working as described in the instruction manual, try resetting it by plugging and unplugging the bracelet from the charger.

Connection Issues:  Before starting, ensure Keen is charged up and close by, and make sure your phone's Bluetooth is on.  Now, force quit the app on your phone (don't just close it).  Plug and unplug the bracelet from the charger.  Open up the app, pull to refresh on the initial screen, and wait up to five seconds to see the bracelet.  

Training Issues:  If training started but does not complete, please contact us.  If you have issues training the bracelet for your behavior, please read the instructions and watch the video in Step 5.

Factory Reset:  If you need to reset the device to its original state, hold Keen's button for 4 vibrations (20 seconds) and release.   

WARNING:This will erase all gesture and event logging information from the bracelet.
