bug report: changing settings (sleep/meditate/maintain) does not work once youve already made a selectiom. a great feature would be able to specify the starting, target AND end frequencies. I want to reach a theta frequency, and come out high alpha, for example. previous review: if I set my ipad to full brightness, create my own program, and close the curtains, it makes for a fantastic hypnogogic experience. Bought it when it was still $10, I really hope the devs continue working on it. A feature that I would love is to create a graph of my program, not just starting and target frequency.
