Rewst keeps track of the people that you follow that have not followed you back. This allows you to stop following the people that weren’t interested in your content. To avoid having a high churn rate and making sure everyone has time to follow you back we wait 7 days, by default, before considering them a non follower.
In your account settings, for each account, you can change this duration. We provide follow back analytics to show you the percentage of people that follow you back within each time frame.
Since Twitter limits how many people you can be following relative to the number of people following you, it becomes useful to unfollow people. The follow back analytics page combined with the non follower duration setting can be useful in making sure you’re unfollowing the right people.
