About FollowerTracker
FollowerTracker.app is a public-data Instagram follower tracker. You enter a public username. The site never asks for an Instagram password.
What FollowerTracker is
FollowerTracker.app is the web tool for Instagram follower checks, recent follows, unfollowers, and accounts that do not follow you back. Recent Follow Tracker App is the iOS companion for alerts and saved history.
How public data tracking works
FollowerTracker compares publicly visible Instagram profile data over time. Private accounts cannot be analyzed from the web tool. Instagram does not send unfollow notifications, so external comparison is the only practical way to detect lost followers.
