Apple is notorious for shutting down things they don’t like. This tends to anything financial related that they don’t control. This is a major contributing factor in iOS users(iPhone owners) paying more for the same function that Android users get cheap or for free. AppGratis is a case in point. A new service, Tekiki, has a service that may be immune to Apple’s iron grip control.
If you don’t already know this, apps change price and go on sale often. If you’re interested in an app or want to browse for a general capability then go to Tekiki and have a look. Be patient and your iTunes bill will drop.
