Professional App Store critic Kosta Eleftheriou discovered an iOS app that refuses to open unless you give it a 3 to 5 star review first. The app uses iOS̵
Now removed from the App Store, the UPNP Xtreme claims it can stream content from your phone to a TV using the UPNP and DLNA protocol. But when opening the app, users are immediately greeted by the iOS system review prompt. If you try to close the prompt, nothing will happen and it will only respond when you press the three star, four star, or five star icon.
The review: “This app forced me to give it a good rating before using it.”
You: “Phew, no one is forcing you!”

Kosta Eleftheriou says it’s easy for developers to manipulate the iOS review prompt to perform this kind of behavior. The fact that Apple doesn’t automatically check for this kind of manipulation in its approval processor is alarming. What’s worse is that anyone who opens the app will immediately notice the problem: has Apple even tested UPNP Xtreme?
