While Twitter itself doesn't say that you're no longer being followed by someone, there are other services that do. Free apps like Statusbrew and WhoUnfollowedMe will indicate on a dashboard who is no longer following you. If you're looking for a business solution, you can upgrade to a paid account (or sign up for a premium service like Twitter Counter). If you prefer to receive a daily email with a list of people who have stopped following you that day, try a service like TwittaQuitta or Zebraboss.

Tips
- If you unfollow someone, prepare to be unfollowed yourself.
- When looking for alternatives to these sites, make sure you don't sign up with a service you don't trust. Some sites and apps claim that they can tell you who is no longer following you, but in fact they just want to collect your personal information.
