A full version app for iPhone, by Interstate Industries Inc..

With Hemi-Sync Unlimited, you can enjoy hundreds of high-quality, immersive binaural beats. The app combines two tracks of the same frequency but opposite in phase to create an illusion of sound where your brain creates a third, synthesized track from what you are hearing. Each beat in the app is carefully designed to help you relax and focus.

There are several ways to use Hemi-Sync Unlimited. You can listen to your favorite tracks on your device, or stream them directly to your headphones. Also, you can combine several tracks into one and enjoy a free daily track.

Hemi-Sync Unlimited is designed for relaxation and meditation. It is not intended to be used as music for driving or heavy metal.
