@Justunfollow - Twitter app to find people who unfollow you

"JustUnfollow is a simple twitter app to find people who unfollow you or don't follow you back.Find your fans, check if particular user follows you & whitelist non followers. I made this twitter app because I wanted to find users who unfollowed me on twitter. Finding people who unfollowed me was not easy and hence the idea to make a twitter app to solve the problem. "
