I used to use a app called "White Noise". I played it at nite,on my iPad. It helped me sleep & Id rate it 5 stars - its even better than this. But what I like about this app is that it works seamlessly with my old iPod touch & my iHome clock (which is like a clock radio on steroids). So now I use one device, my iPod touch docked on my iHome stereo (that has alarms). I set it for an hour & the sounds go off. There are many sounds & many pics that become the wallpaper behind the digital clock. You can also use a pic of your own). The app was free, $1.99 to remove ads & Im sure you can buy more sounds & wallpaper. I havent found that necessary because the free version already has plenty. I would highly recommend if you use an iHome system.
