Mirror Free is an ad supported free app on the App store. The app simply creates an empty picture frame on the iPhone. When you look into the empty frame, the screen’s reflection supposedly creates a mirror effect. The app has somehow become a hit. It is one of the top free apps on the app store.
The app does absolutely nothing. Seriously nothing. It is literally a blank screen. Even the app’s description warns people not to download it. But the app still manages to make top ad dollar.
According to AdWhirl, the ad click through rate on the app is surprisingly high. AdWhirl?s co-founder himself said that the app could make as much as $2,000 a day from ads.
