My recommendation is that you try the white noise machine before you buy it. I made a mistake of ordering one from Amazon and although it was very highly rated, the noises it made were annoying to my ears, as they were very "metallic" and they gave me goosebumps. I like Headspace for an app. It has meditations, but also things for helping you sleep and white noises that are more "organic", like rain, wind, rustling leaves, etc.
