Track a public account’s followers and following over time, with names, not just a count.
Each account in PenguinRadar Instagram Follower Tracker gets a change overview. It charts follower and following counts over time and lists the names that joined and left in each period.
On Lite, Starter and Pro, PenguinRadar Instagram Follower Analyzer adds who follows back, and each period gets a short AI summary.
Track Instagram followers in three steps. You see the price before each scan.
Sign up with Google or email. Eligible new accounts get 50 free credits for PenguinRadar Instagram Follower Tracker.
Enter a public username and pick followers, following or both, so it works as an Instagram following tracker too. Each list shows its price, and the first complete scan is the starting point.
After the next complete scan, open the activity timeline in PenguinRadar Instagram Follower Tracker. New followers, new follows and unfollows each get their own filter.

Three new followers and three lost ones leave a count unchanged. Comparing lists shows all six names.
Above 10,000 followers, profiles show a short count like 12.3K. This reads the exact number.
Instagram gives only one short page of a verified account’s followers. Rather than guess, this tracks who they follow.
