FollowerTracker tracks follower changes for public Instagram accounts. Save private snapshots and compare follower, following and post counts between manual checks. Follower samples provide leads to check, not proof of unfollows. AI audience insights cover gender mix and interests. Tools also analyze Reels, comments and competitors, with CSV export. No Instagram password needed. Registration is required; signup credits cover the first check. Credit packs start at $19.99 and monthly plans at $14.99.
