Besides these two tabs, Unfollowers for Instagram has a few other interesting ones: a tab showing all 'mutual' follows and one with people who follow you but who you don't follow back. The last tab, for 'ghost' followers, shows you which of your followers haven't left any comments or likes on your last ten posts.
Unfollowers for Instagram is an interesting app for frequent users of the popular social network. Thanks to it you can keep close track of who's following you and who you're following yourself.
Requires Android 4.0 or higher.
