Brainwave Tuner v1.3 is specially designed for users to relax body and mind and stimulate thought. Once tuned in, the brain will be closed into a quiet status and become calm.

New in this version:
• Each wave preset is thoroughly tested to eliminate the glitches between each loop.
• The sound quality of each wave has also been greatly enhanced and optimized for iPhone/iPod.
• Three white noises are added: Ocean Waves, Shoveling Sand, and Rain and Windshield. (There are 19 brainwave patterns available)

It is on sale for $1.99 at App Store.
