Very handy little app that allows you to sort your followers into three camps (Jerk, Mutual, Fans) depending on whether or not theyre following you and/or youre following them. Nice way to keep on top of the fickle followers who follow you for a week or so expecting a follow back. Might take a while to weed through them if youve got lots of followers or are following lots of people. I had a bit of an initial problem accessing all three of my Twitter accounts (the app puts them all in one place, just like the Twitter app) - one of them wouldnt login. I followed @MutualApp on Twitter and tweeted them the problem and they were quickly able to walk me through fixing the problem. If theres a disconnect between your Twitter password in Settings and your password in the Twitter app, Mutual isnt able to login to check your followers. Once I re-entered/updated my Twitter password in Settings, it worked perfectly for all three accounts. Also, worth noting that if you follow @MutualApp on Twitter, they will follow you back ... I think theyd rather be Mutuals than Jerks. Ill keep an eye on them with this handy little app!
