Tweepi
Tweepi provides a slew of powerful tools to help you manage your twitter account and grow your twitter user base.
FOLLOW RELEVANT USERS Tweepi offers a collection of simple tools to help you discover and follow new Twitter users: follow a @user's followers/friends, follow members of a Twitter list, follow by tweet and follow by user-bio search.
FLUSH THE UNFOLLOWERS Users not following you back? With Tweepi you can quickly list users that you follow but do not follow you back and take action.
RECIPROCATE It takes a long time to find all the users you're not following on Twitter and then following each one back individually. This tool helps you find them easily so that you can follow them back quickly.
CLEANUP THE INACTIVES Many Twitter users do not engage in conversations, never retweet anybody, or simply just ramble about nonsense all day long. Use Tweepi's "Cleanup" tool to filter those people out and unfollow them.
FORCE TO UNFOLLOW YOU Undesirable users with inappropriate avatars showing up on your 'Followers' list? You can use Tweepi's Force Unfollow tool to filter these people out and force them to unfollow you.
