Doesnt work at all

The application shuts down before even analizing the address book to make any changes. If the paid app is any better, the free versions is not doing it any favours! I wanted to try the free version before choosing to buy a more solid paid version. I should have known that if the developers failed to even make clear what was the difference between the versions, the apps couldnt be any good.
Doesnt do what it promisses. In fact, it doesnt do anything at all. Waste of time.
