It's very good

Tim C. (Verified Buyer) 5/5

Very easy to use, helps me with breath control and focus, very pleased.

Helpful for my daily stress

Charlee (Verified Buyer) 5/5

The device itself is sleek and easy to use. I love how it fits perfectly in my hand, and the real-time biofeedback is incredibly insightful. It’s fascinating to see the baseline of how stressed my body is, fluctuate throughout the day and how specific breathing exercises or moments of mindfulness can quickly bring me back to a calm state to reach pink or white lights. I also bought this for my mom who suffers from tension headaches and lower back pain, and she's noticed a significant reduction in both since incorporating Calmstone into her daily routine.

I recommend!

Nancy (Verified Buyer) 4/5

It works well if you can be in a quiet place and you have to clear your mind. I was able to get better getting to the calm level as I keep using the Calmstone. I have to set aside 15 to 20 minutes to get the best benefit.

Great little tool

Simone (Verified Buyer) 5/5

I bought the calmstone for my son who is suffering from chronic pain. As a chronic pain coach myself I have to say that it is amazing! The visual biofeedback is a really intuitive way to implement calming techniques such as breathwork and see how it affects your nervous system in real time. I am ordering more for friends and will recommend it to clients. Everyone needs a calmstone.

Game changer!

Seriously recommend for anyone and everyone looking to cultivate a mindfulness practice!

Our Story

Making It Simple to Overcome the Chaos of Life

During my PhD program, I recognized the benefits of biofeedback technology for managing stress and anxiety. However, much of it was either too expensive or complex, so I created a product that is affordable, accessible, and easy to use regularly. The need for effective mental health care is more pressing than ever, as many of us feel overwhelmed by daily demands. Creating Calmstone is personal for me; I've faced mental health challenges and witnessed patients struggle as well. My published research has demonstrated significant improvements in anxiety, sleep, and chronic pain through biofeedback technology. In 2023, Calmstone was featured on MedScape and endorsed by medical professionals. Calmstone empowers you to overcome daily mental challenges by making it simple to calm your mind.
