I was expecting a more outrageous design for a speaker named Outcry Extreme ($54.99) from a brand named Wicked Audio, but that's what you get for making snap judgments. In reality, the Outcry Extreme looks like a high-end speaker from Sonos, but it's a fraction of the price. There is one styling cue that is subtle, but it's there. The Wicked Audio logo is embossed in the metal grill, if you're looking for it. 

All of us have had to plow through at least one difficult day of school or work after a less-than-optimal night of sleep, or even an all nighter. But what happens when a rough night becomes the norm? The Centers for Disease Control collects data about the sleep habits of Americans, and reports that one in three of us are getting fewer than the recommended seven hours of sleep per night. Whether you can't fall asleep, can't stay asleep, or both, insomnia is not only miserable, but bad for your health. I'm one of those insomniacs that can't stay asleep; waking up more nights than not after only about four hours of shut-eye, and not being able to drift off again for at least an hour or two. If you're like me, and have spent many wakeful hours wishing you could just relax and sleep, it's time to find some help. While relaxing bedtime routines, meditation for sleep, natural insomnia remedies, calming teas, and even sleeping pills can help, there's one more thing I think you should try: a sleep app for your iPhone! I tried Sleep Genius for two weeks, and am still using it every night. Sleep Genius is a sleep app that combines soothing sleep music, a gentle alarm, a relaxation program for anxiety at any time, and even a power nap feature! Read on to learn more about Sleep Genius, and why I think you should give this sleep app a home on your iPhone.
