This product has not been formally studied: no claims are being made as to the effectiveness of this application. The iNeuro40+ combines three factors well-founded in scientific clinical studies for the basis of reversing mild cognitive impairment (MCI) and its relationship to memory and cognitive deficits. The first factor relies on the research around 40Hz and its relationship to MCI: this app generates 40Hz sound. The second dimension is the result of combining two frequencies, creating a binaural frequency aligned with brainwaves for relaxation.The third feature presents those frequencies as specific rhythms for a full positive physical reaction to which individuals are stimulated to “dance”, thus stimulating the immune system. Our website provides resources for those wishing to follow with such details... most notably the large number of resources around 40Hz. Also, a simple search on iTunes will yield a large number of audio tracks available using this frequency. We invite you to listen there to all the diverse music leveraging 40Hz in the iTunes realm. This app has a tool enabling the user to provide, at their sole discretion, data relating to their session. This feedback would help us validate this methodology. It should be noted: this technology is publicly available. These concepts have all been introduced separately. We believe delivering all three of these elements (40Hz, brainwave stimulation aligned in a particular range for relaxation and applying a rhythm) simultaneously, will result an optimized level of relief. Of course, optimized being the keyword as there's an assumption that the three features we combine here provide relief on their own.
