Do Not install.

This app is the closest thing to malware Ive ever come across in the App Store.
It continually and randomly prompts for your iTunes password.
It should have never been allowed by Apple.
Based upon other reviews Ive read, I gather that the prompting for your iTunes password is a greedy attempt at extorting money. Run far far Away.
