I only ask because I see Mirror Free is still at the top of the chart in the App Store. Quite why people are so fascinated by this app is completely beyond me. In my opinion, nay, in fact, this is the worst iPhone application of all time. It's an application so pointless that its functionality can be replicated without even turning your iPhone on.
In case you've not heard of it, Mirror Free is a program that places a series of poorly-designed picture frames on your device, allowing you to see your face in the black space in between. It looks terrible and offers no functionality whatsoever. Even the developer of the program has admitted that "this app is a piece of crap".
Of course, it's not the first pointless app to become mega popular. There was iFart, which replicated the sound of flatulence; Spin the Coke, which was designed for risqué college party games; and iBeer, which made your iPhone look like it had beer in it. Like Mirror Lite, all of these stupid programs reached the top of the iTunes chart. The logical conclusion, therefore is that most iPhone users are a bunch of vain, vulgar, promiscuous alcoholics. Feel free to disagree with me, but I think you'll find the evidence speaks for itself.
