Sure, for anyone that understand the basics of computer programs it's obvious that you can't copy an app from your friend just by snapping a picture of the icon, but I don't think it's a good idea to rely on this assumption.
Of course if he didn't get it it's only my fault because the description is not clear enough (I'm not a native speaker) or the UI is not easy and intuitive as it should.
Any help would be highly appreciated!
1) The configurations or any settings will be copied along;
2) You won't have to pay for it.
I wouldn't bother with #1, but the review guy was probably pissed because of #2.
Your English is flawless, but I think you forgot that "sharing" is used in "file sharing" and is bound to attract people that don't want to pay for things. Thus they get double annoyed when they pay for an app that does not let them not pay for other apps.
1- you snap an app from your friend's iPhone screen and tap on the Install button (i.e. app sharing)
2- snap an app from your computer screen (a review site for example) then Install/Bookmark
I'd be concerned about getting many users to install/use it, though, because it always takes up a space on the Home screen, when it'll only very rarely get used. I wonder if we'll see more uptake of apps like this when users get on OS 4 with its folders... I could see myself keeping a few folders of "rarely used utility" apps. As it is, I wouldn't keep this app on my device just because of the "clutter" aspect.
The App Store comment saying it should be cheaper made me laugh.
My email is in my profile for who's interested.
