I wish I had this decades ago. Really grateful for how it’s helped me build my awareness. Even half the time I sorta knew I was pulling but the vibration helped me rethink it and switch to a better strategy for me. Also love their emails and blog and I just did their monthly community challenge and I’ve never felt better about my ability and control over this evil disorder that pained me for so long. This is a game changer and so worth the price. Great company and community. And the app improvements are noticeable! ### 5/5 — Amazing *2024-10-20, version 1.1.12* It is great I just got it and I love it ### 5/5 — I’ve never seen anything like this!! *2024-05-13* I totally thought I was alone in this. I’m floored by just how many people suffer from this disease…it’s a real thing I have. This app is AMAZING!! The KEEN2 is AMAZING!! ### 5/5 — Helps with skin picking *2024-04-11, version 1.1.9* This bracelet + app combo made me realize how little I’m actually conscious of where my hands are in space. The bracelet vibrates so often while I’m at work which is a good thing bc that’s when I’m picking the most! Helps me know when it’s time to put my hands down and take a break ### 5/5 — Incredible! *2024-04-11, version 1.1.9* Keen2 is a gentle reminder all day long! My husband no longer nags me about biting my nails. Instead, this life changing app, does it all! I am so thankful to have found this! ### 5/5 — This is a game changer! *2024-04-11, version 1.1.9* For years I tried everything to stop pulling. This AMAZING app and bracelet is what helped my behavior change stick. The app is easy to use and the bracelet vibrates everytime! The company also helps with set up for free and is super helpful. They mean it when they say we are part of the keen family. Highly recommend and don’t give up! ### 5/5 — Great product *2024-04-10, version 1.1.9* The app is well designed and connects to my bracelet. Overall it’s helping me with my hair pulling a ton! ### 5/5 — Grateful for this *2024-04-10* Super helpful and the improvements are noticeable ### 1/5 — I had very high hopes for this, but the app has never worked *2023-04-05, version 1.1.5* I purchased Keen2 over a year ago with very high hopes and excitement for such a unique and innovative solution. Unfortunately, the app has hardly worked to track data for the entire time I’ve owned a Keen2 and there have also been recurring issues with the band. This app needs to be replaced with a new app that actually works. Resetting and troubleshooting, to no avail, is frustrating. If you purchase a keen band, do so with the understanding that you might not be able to use the app as advertised. ### 5/5 — Updates are noticeable! *2022-07-11, version 1.1.2* I’ve had this app for a long time now, there have been a few updates to the app recently which have made it much more reliable. Big fan! ## Frequently asked questions about Keen2 ### How does Keen2 help with hair pulling? Keen2 allows you to manually track each instance of hair pulling to identify patterns and triggers.
