Who’s not following you back on Tumblr, find out with Friend or Follow for Tumblr.
Thanks to v2 of Tumblr’s API, we’ve launched our popular Twitter follower management app, Friend or Follow, for use on Tumblr.
You can now easily see who’s not following you back, who you’re not following back, and your mutual followers. Expect more features and updates to come!
