This is a fantastic, free app (with a $0.99 pro upgrade) that does what it says very well: It provides quality, customizable white noise that helps you focus!

Do you have trouble going to sleep? Are you traveling on a plane and need a quick power nap? Does your newborn baby wake up in the middle of the night? There are numerous benefits to using White Noise:

• Helps you sleep by blocking distractions
• Relaxes and reduces stress
• Pacifies fussy and crying babies
• Increases focus while enhancing privacy
• Soothes headaches and migraines
• Masks tinnitus (ringing of the ears)

Even when you’re asleep, your brain is constantly scanning and listening for sounds. If it’s too quiet, unwanted noises such as faucet drips or police sirens can interrupt your sleep. White Noise generates sounds over a wide range of frequencies, masking those noise interruptions, so you can not only fall asleep, but stay asleep.
