The app, at the first launch, extracts the list of followers, then, with subsequent scans indicates if there have been any changes.
The extracted lists contain different types of users:

★ Unfollowers: who started to follow you and then stopped
★ Blockers: Followed who blocked you
★ Followed Unfollowers: the unfollowers you follow
★ Followed without benefits: those you follow and they do not
★ Followers: (Fans)
★ Followed Followers: (Mutual)
★ Unfollowed Followers: (Super Fans)


You can also:

★ follow/unfollow directly from the application
★ Search new users
★ Check by username if it has blocked you
