I have a few Yoga Nidra apps. This has become my favorite. Very calm and calming, very complete in its content... Yes, I did buy the 3 add-ons for 99 cents total; you need to have those. His voice? If it bothers you any, TURN DOWN your volume a bit so it's soft and quiet. I can't imagine doing Yoga Nidra with loud booming sound anyway. I just had to get used to his accent after a couple minutes is all. Honestly, to the other review - if you couldn't "last five seconds," do you really think you gave it a fair try? Change your focus. Sounds like you desperately need to learn some meditation techniques and actually use this app as well if that's the case! :). Namaste
