Who Unfollow Me For Tumblr App Reviews

I paid for premium and what did a get? Nothing

nothing is right and it doesnt work

Waste of time do not download this app

The info is all wrong and it doesnt tell me who unfollowed me its just blank.

This app worked twice and now only only returns error messages. I emailed the developer and received no response. I actually want my $2 from the in-app purchase back. Apple should take this app down for being a scam or just horribly made.
