Minimal but not lacking
I appreciated the simplicity of this app. It fulfills its intention, that is, to do what binaural beats do, but without all the distracting whatnots that other binaural beat apps have in the App Store. I have the option to purchase it for 9.99 or use it without its customizable feature. I opted to pay because I felt the developer has made the mindful effort to keep this app simple. I feel it was worth it.
