Other computing devices have screen savers, so it's why many would be "mislead" to think it's an actual screen saver app that magically enables their iDevice to show screen savers.
The subset of iOS users who would consider an instance of iOS hardware to be "a computing device" is quite small, particularly given the app store policies which discourage apps which allow iOS devices to be used for general purpose computing.
And in any event, the App Store contains products of similar functionality, e.g. live wallpaper.
Yes, and look at the reviews. All of them were deceived, they think it's a scam, they demand a refund, they probably feel less safe about buying anything from App Store again, and other iOS developers pay (only slightly) the price of this "scammy" app. Apple should get rid of all such apps – it's better for the business (of Apple themselves and other iOS developers).
Why they approved "live wallpapers", but not "xScreenSaver"? I don't know. It sucks, it seems that their reviews are not consistent.
But just because they made a mistake (like approving "live wallpapers", which IMO is a misleading app created solely for the purpose of milking a few hundred dollars from naïve App Store customers) does not mean that it's okay to do it again.
It doesn't work as a "screen saver" on most devices, as the risk of phosphor burn in is pretty low nowadays. Isn't it still called that in OS X regardless of display type?
Also, a "fart button" is not physical object, can we still call it a "button" (Ceci n'est pas une bouton de pet.)?
How are they right? I really want to understand your point of view.
Do you mean they are not right because the app does not save a screen from anything? What if you are using your iPhone to project something on an plasma screen where a screen saver can save a screen from "burn ins".
The app cannot function as you'd expect a screen saver to do: it won't start running after a period of inactivity. That is outside the scope of functionality available to apps.
Hm. But you can still use it for the purpose screen savers were originally designed to do: save screens from getting burn ins. But agreed: it can't run automatically after a period of inactivity.
Off topic: As a child I loved to look at screen savers that I manually started for hours wondering how they work and how long it took to build them...
I'm glad that my very non-techie friends won't come across this app in the App Store and start having anxiety over whether they need a screen saver for their iPhone. Or, worse yet, start opening it up every time they're not going to be using their phones for a while.
