Everything you need for bin. beats.

Dont know why its crashing for some people. Worked fine for me.

This is everything you need in a binaural beats app. The AmbiScience ones just have programs that take you up and down in Hz.

One big caveat: the slider labels ( Sleep, Normal, Active) are not correct for everyone (or even most people, I believe). Turn the Hz display on in options and do your own research for levels.

Most people will fall into this:
1-4 Hz (Delta brain waves): Sleep
4-8 Hz (Theta): Relaxation/daydream
8-12 Hz (Alpha): Calm/Aware
12-15 Hz (Low Beta or SMR): Focus
15-40 Hz (High Beta up to Gamma): Busy body mode, may cause anxiety
