Here are 3 of my favorites twitter unfollow tools. I just use the free versions, which have unfollow limits. When I want to unfollow more than their limit I use another tool listed below. Usually, I don't unfollow more than fifty people a day. And only unfollow people about once a week. I have recently updated this list. I remove all three of the tools I listed before because they didn't work due to Twitter changes or they were no longer free.
iUnfollow is simple and easy to use online tool that allows you to quickly unfollow batches of users who are not following you back on Twitter.
Unfollower Stats is the next tool I use. Unfollower Stats is a free to use third party twitter app to track unfollowers & unfollow them. Unfollower Stats also offers more Twitter tools located on their sidebar.
Commun is an easy to use Social Media management tool. Their unfollow tool is very easy to use. The free version only allows 10 weekly unfollows.
