I havent used this particular app yet, but Ive used several others by this developer and have found them all to be top notch. I use them for studying, meditation, napping, and sleep induction. Try this or any of their other apps, you wont be disappointed. If youre new to binaural beats, give it some time and withhold your skepticism. Use noise-canceling headphones for the best experience. Also, the volume of the beats doesnt have to be very loud. As long as you can barely hear them underneath whatever music or nature sounds, etc., you have on top of them, they should be effective. Dont just take my word for it though, do your own research.
