Tweetstats is one of the earliest Twitter analytic tools to be developed and its still fairly popular for good reason. Just by entering your Twitter username you’ll be given several colorful graphs which show how many tweets you make per hour or month, which day you tweet the most, what platform you use to tweet as well as who you talk to the most on Twitter.

It’s fantastically to easy to use and gives you a quick overview of your Twitter activity, how you use Twitter and who you talk to you. You can also input other usernames to get a glimpse at when they often use Twitter and who they interact with.. a good way to find Twitter friends as well.

Twitter friends is an analytics tool which gives you more information on your Twitter social network. What kind of information? Who messages you the most, who you talk to the most, the average number of daily tweets and even your average tweet length. It also allows you to retrieve an archive of all your conversations with a specific user, just by entering his/her username against yours.
