You are certain to appreciate a service like this one if Twitter is your reason d’être. In principle, what this aptly-titled Twitter tool does is notify you whenever you lose a Twitter follower.
This is done automatically via the Internet – that is, you first supply your Twitter username and then this notification service will send you a direct message letting you know you have lost a follower.
As far as the rate of updates is concerned, you will receive them within an hour of being dropped. The number of followers you have is also part of the equation. That is, for every 1,000 followers you have it will take one additional hour for the update to be sent.
The idea is not really far removed from others like Qwitter, but I think it is important to have alternatives and check out different tools and applications as they become available in order to see which one is right for you. If you want to give this one a try, just start following @tless for notifications to be put you way.
