FollowerTracker

FollowerTracker tracks follower changes for any public Instagram account. Enter a public @username and it saves a private snapshot of the follower, following and post counts plus a sample of followers. On your next check it shows the exact count changes, the names that appeared in or dropped out of the sample, and an AI read of the audience: gender mix, top interests and a one-line verdict. With a credit unlock it also estimates how much of the audience engages, by comparing the follower sample with likers on up to six recent posts. Separate tools analyze Reels, comments and competitors, with CSV export. It reads public data only: no Instagram password, no browser extension, and the account you look up is never notified. Sign up and your free credits cover the first check; credit packs start at $19.99 and monthly plans at $14.99.
