If you're looking for a little help falling asleep, or need something to help you squeeze the most shuteye out of a power nap, Sleep Machine for iOS offers up ambient soundscapes, relaxing music and a built-in sleep timer to help you fall asleep, enjoy your nap, and wake up rested.
Once installed, Sleep Machine offers 91 different ambient sounds and 9 different audio tracks, all of them filled with ambient sounds designed to help you relax and drift off to sleep. The app supports multi-tasking in iOS 4, so you can play a soundscape while listening to your own music underneath it if you like. If you're the type who can't fall asleep without the sound of a fan going, or the sound of a train passing over the tracks puts you to sleep, Sleep Machine can play those sounds and more.
Sleep Machine isn't the only smartphone sleep assistant we've discussed. Pizizz and SimplyNoise are alternatives, but Sleep Machine will only set you back $1.99 in the iTunes App Store, compared to Pzizz's $6.49. The purchase price gets you access to all of the app's features, as opposed to Simply Noise, which is $0.99 but requires in-app purchases to get soundscapes and added music.
The only downside to Sleep Machine when compared to either is that Sleep Machine doesn't offer pink noise tones, although it does have multiple white noise tones. Android users looking for a similar app can try Pzizz for Android, or download Lightning Bug, another great, free ambient noise generator and sleep aid.
