Perfect!

Ive been carrying around a white noise machine for years on trips. Its bulky but super effective. A friend suggested I start tiring some apps. The brown noise at 70% on this app is so similar to my physical device, its just awesome. Another thing I really like is youre not using any data of your data plan when youre using it. You can prove that by turning your phone to airplane mode while using it.
