Twitter sends you an email when you have new followers, but when someone stops following you, it’s difficult to know who it was, specially if you have a lot of followers. There are services who tell you who stops following you, like @unfollowr for example. You have to wait hours or even days to know, and sometimes they don’t work at all. This program runs on your PC and tell you when somebody stops following you. It works on Windows XP/Vista/7. To start, you must enter your Twitter Username (no password needed). You can adjust the checking interval. The program places an icon on the windows Tray and when someone stops following you a baloon message pops up.
