Although twitter is one of the simplest networks to use, there are thousands of external applications that provide us with many interesting features to improve our results.
Perhaps the most powerful suite to manage our Twitter account. Although it is paid, its monthly price (from $ 7 per month) is well worth paying. It allows us a multitude of things, but it is essential in the management of followers, segmentation and filter and creation of direct message campaigns.
Although we also have this functionality in Socialbro, in FriendOrFollow we can see quickly and free the users that we follow and do not follow us back and vice versa.
One of my favorites to know quickly if one user follows another.
An application that will allow you to know the degree of influence of a user on Twitter. It will serve as a combination with Klout to compare data.

A simple application that tells you how many fake users have an account.
A Buffer competitor that allows you to program tweets and monitor keywords.
