Here are 3 of my favorites twitter unfollow tools. I just use the free versions, which two of the tools have unfollow restrictions. 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.
JustUfollow is my favorite, I like it because it displays information about the person twitter account, which helps me decide whether to unfollow or keep following that person. It shows you how many tweets, following, and followers that person has. And if you click their link it displays their twitter profile. You can also click on their @twittername to go to their twitter page and read more tweets if you like. There is a fifty daily unfollow limit for the free version
iUnfollow, I just started using this tool. They provide a link to the twitter account so you can check them out before you unfollow them. They have a 75 daily unfollow limit.
Friend or Follow has been around for years, it's the first unfollow tool I used. No unfollow limit. Their main page displays pictures of people who aren't following you. When you click on their picture, it will open their twitter profile in a new window. You can then unfollow them on twitter. They are coming out with a new updated version soon.
