I bought the Tipa Tinnitus product through Apple iTunes recently. The app is free to download to your iPod, iPhone. Once the app is on your device you purchase "Playpacks" of 50 plays from within the app ($50). It is very easy and simple to use. I have only used it 3 times so far. I have not had any results positive or negative. I can hear some mixing of the tones with the tinnitus and the tinnitus tone changes while I am listening. No residual inhibition for me at this point. Of course if I get any positive effect I will post it here and everywhere. But I'm not holding my breath. Normally I would not buy into something like this without supporting evidence of it's effectiveness. I saw this advertised in the ATA publication so I thought that lent it some credibility. Maybe not.
