About this app

Keen2 by HabitAware provides two ways for YOU to take control of hair pulling (trichotillomania), skin picking (dermatillomania), and nail biting:
(1) On your own: Download this app for FREE to manually track how long “I am HabitAware”
(2) With the Keen2 smart bracelet: Order at to empower healthy lifestyle change

Here’s the details:
We’ve specifically designed the app to allow anyone with hair pulling, skin picking, or nail biting to MANUALLY track their behavior. Just download the app for FREE to get started.
Each time you realize you are hair pulling, skin picking, or nail biting, just open the app & tap the ‘+’ button to track it and add contextual details.
The data you input will help you understand patterns and triggers. Once you know WHEN the behavior is happening you can PRACTICE healthier ways to REPLACE the behavior and take control.

Co-invented by a mental health advocate with trichotillomania and in collaboration with renowned researchers through a National Institute of Mental Health research grant, HabitAware’s Keen2 is your awareness & response trainer.
Keen2’s app + smart bracelet is a holistic system that shifts you from autopilot to awareness. With awareness, you have the power to control your behavior and practice evidence-based Habit Reversal Training strategies (available as an in-app upgrade).
Keen2 uses patented gesture detection technology to recognize when you are hair pulling (trichotillomania), skin picking (dermatillomania), or nail biting. Keen2’s vibration is like a “hug” on your wrist and your “self care” alarm. As you build awareness of your restless hands and use the vibration as a cue to practice healthier soothing mechanisms, you can Retrain Your Brain.

It constantly connects and disconnects with the band. The band is also not very responsive to my tapping, so I can't usually see past the first page. EDIT: band still doesn't connect fully with app. Also, the band suddenly started vibrating nonstop. I had to go into the app and click Vibration Test to stop it from vibrating. It went on for maybe 30 seconds. Really terrible app and band overall.

This application is part of my everyday wellness. This paired with the Keen2 watch has really helped me with managing my BFRB. Great app and great product.

This app is an excellent concept, and after a while of testing the settings, I've managed to get the motion detection accuracy pretty accurate. This has helped my awareness massively. However, the app itself lags and doesn't always respond when I select things. The app won't connect to the cloud so I have no way to back up the data. PLEASE make a way to export the data off my device, I want to use this amazing data to find patterns in the behaviour and share it with my therapist.
