Binaural Beats -- Brain Waves

This app has a wide selection of music but little information is given with each piece of music. It says gamma Brainwaves but there is a wide range in the gamma spectrum 30 & up. Or "focus " but no other information... Is there beta, or gamma, or alpha Brainwaves. My opinion is that it makes a big difference and that listener should have that knowledge.

Hope this helps

Wow this app is absolutely incredible. I have been searching for ways to enhance my study sessions,and stumbling upon this brain alpha waves music has been a game-changer
