"Statusbrew – Here is a total social media management platform that will let you engage and grow with your audience."
"Unfollowers.com is helping firms make sense of Twitter by analysing user activity."
"In case you weren’t aware, there are tons of websites and apps that can alert people when someone unfollows them on Twitter—for example, Unfollowers.me."
"Unfollowers.com has a similar service for Twitter, allowing you to discreetly check who has unfollowed you. The site also allows you to check who is not following you back."

"Although Twitter sends new follower notifications, learning who unfollowed you will require a little extra work. There are a number of websites such as Unfollowers.com that allow you to see who unfollowed you and who you don’t follow."
"Unfollowers, a follower tracking service for Twitter, Facebook, and Instagram, has achieved the rare feat of becoming a dominant player in a deeply fragmented market."
"This one's pretty straight forward, and it's free. Just sign in to your Twitter account through the Unfollowers.com site, and you'll be able to see 'Recent Unfollowers'"
