Has anyone tried using binaural beats to help facilitate relaxation and calm the mind? There is a relatively highly rated app on the iTunes App Store but I don't want to spend the money if there is no chance it actually helps.

I have used an hour long track on Amazon Prime Music with rain sounds and theta waves which seems to relax me but it could just be the rain. I'm actually thinking I'd rather NOT have the ambient rain, I'd rather have silence though with just the binaural waves if that is working.

Thanks for your help!
