Apple warns developers over 'creepy' apps

Apple has warned software developers that apps deemed "too creepy" will not be allowed on its online store.

In an update of its app store review guidelines, Apple said: "If your App doesn't do something useful, unique or provide some form of lasting entertainment, or if your app is plain creepy, it may not be accepted."

Apple removed an app in 2012 which showed the location of women who had checked into Foursquare.

The software giant also warns developers who may have "amateur" apps rejected.

In its updated guidance, published on its website, Apple adds: "If your App looks like it was cobbled together in a few days, or you're trying to get your first practice App into the store to impress your friends, please brace yourself for rejection.

"We have lots of serious developers who don't want their quality Apps to be surrounded by amateur hour."
