Electromyography, or EMG biofeedback, is commonly used to treat headaches, back pain, neck pain, jaw pain, anxiety disorders, and for muscle retraining after injury. An electromyogram (EMG) sensor measures muscle activity and tension, and teaches you to relax or engage specific muscles at will using visual and auditory signals.

In the past, EMG biofeedback training required expensive equipment and had to be done in physical therapy or at a clinic, but now can be done at home using our affordable wireless EMG biofeedback device with your smartphone or tablet.

Our simple interface is easy to set up and use. Muscle activity is displayed in real time on our mobile app, and a threshold alarm can be set with an audible signal or vibration when the threshold is exceeded. More advanced users can save sessions and download detailed EMG data.

    I started using this sensor along with the app to help decrease my stress and let me say it is so easy to use! I was a little worried at first with placing a sensor and making sure I had it in the right place but it was simple! I can honestly say this app has helped me decrease my stress in the time I have used it. I recommend for everyone dealing with stress!

    This is a wonderful product! It’s very helpful in training my mind to relax the parts of my body that are constantly uptight from stress. The content is well researched and the prompts are straight forward and easy to follow.

    Please, i would like to know if the app shows some unit of Hertz?

      Hi Lidia, we do not show the units in microvolts on the app itself, however there is a way to log onto your account via a website where you can see more detailed versions of the graphs with the units, and we will soon be adding the ability to download the raw data which will give you the exact microvolt measurements. Please contact us at if you have further questions. Thank you.
