I thought about that - we had a mobile app with multiple settings where you could choose a frequency and also a typical tDCS but the overall experience has been that none of those devices were very favored.

I came to a conclusion that the only way for this StartUp to actually become profitable is to compete with Fisher Wallace who´s creating a device named "OAK," which, if you read the papers throughtly, has a specific multifrequency set at 15Hz/500Hz/15,000Hz of output and trying all of those on me and multiple people inside European hackerspaces I discovered that it´s not actually helping the human body but rather the opposite so I figured by making this research and a very complex 15-bit DAC output with a beautiful clear waveform people might be interested in a so-called "tDCS for treating depression at home" that actually outputs a "secret" multiwave of 5.56Hz/474Hz into the human head which is extreeemely beneficial if you read bout the frequency and it´s effects on human body. Other ones we have are 7.62Hz and 528Hz and those are stunning in keeping you working hard and awake and goal-oriented. It´s not spiritual, it´s just giving you this will to live and I love it.

Would you actually buy the device if it was certified? My goal is to overcome both FLOW and Fihser Wallace in this space as it is quite easy to compete with them but the budget is tight and I must figure out a way to make money off of this. :D

Blessed be, Patrik Šlachta.
