Brainiac

This App is incredulous! The stereoscopic surround sound is incredible and it is the only app which helps me sleep and relax. I have severe tinnitus from a brain injury and I use this app every night to allow me to settle enough, in spite of the intense ringing in my ears, to fall asleep.
I let it play the entire night and I especially enjoy the other apps this developer has created.
Most definitely worth it to upgrade.
