This week’s App of the Week is Sleepmaker Waves. This free app is a Godsend to those of us for whom a bit of white noise is a pre-requisite to falling asleep. You get 45 or more minutes of play time from your choice of ocean noises before the app turns itself off. Just plug in your phone for the night, set your alarm, and pretend that you’re laying in a hammock overlooking the Caribbean rather than some random hotelroom in the middle of nowhere. Download Sleepmaker Waves, and let your imagination lull you into a seaside siesta.
