If we have been tracking your Twitter account before, then you will be able to see your Follower, Following and Tweets stats immediately after sign up. If this is not the case, please allow a few hours until your graphs start displaying stats. As soon as the account has become premium we will track the data hourly.
Be
aware though that we can't go back in time indefinitely. If
we have not tracked your account before you signed up, the start date will be
the date you have signed up. From now on you will be able to see how the
interactions with your audience will affect your follower growth.
