I downloaded this app a few months ago, but I had a hard time listening to it everyday like they tell you to. Since the new year I have been more committed to it, and I have seen smoke free for 8 days, cold turkey. I did shell out for the paid version a few days ago, I couldnt stand listening to the instructions every time.
I dont think its a magical cure, but if you really want to quit its worth a try!
