I love these apps!

I have all of the solfeggio apps, love each one. I fall asleep to them every night, and will often listen to the instrumental portions while working. I am in withdrawl with iOS8 causing the apps not to work :) I know Glenn is aware and the problem is being worked on. Once they get it all sorted, I highly recommend these apps. They are well worth the investment as are all his apps.
