After installing the app, I was able to adjust the BrainWaves to a specific frequency. After enjoying my selection for an hour, or so, I attempted to adjust the frequency; but as I adjust the frequency, there are no numbers to show what frequency I am actually at. Plus, less than two hours after paying for the app, I got a pop-up that says that this version will no longer be supported. It directed me to download the new upgraded version, again had to pay for it. I’m pretty sure that as soon as I pay for the new upgraded version, a pop up will again show up telling me that THAT version is no longer supported…..but for a small price….
