Sleep Now is the perfect application for taking naps, going to bed a night, or for resting while travelling. Not only does the app have several relaxing sounds such as white noise, rain, waves, etc., it also plays any music on your Android device and even creates playlists on the fly. Sleep Now can detect when you fall asleep allowing you to fine-tune how long you want to take a nap. You can set a silent alarm that vibrates faintly so nobody hears the alarm but you. Or use Sleep Now when going to bed to first relax while listening to an audio book. Sleep Now will remember where you stopped and automatically continue on the next day.
