IggyPlug Tracker monitors an Instagram account and emails a full report every week showing who unfollowed, who newly followed, and where the follower count stands. Each unfollower appears with their username, display name, profile photo and the date the unfollow was detected, rather than just a total. A private dashboard keeps the full history and can be filtered by the last 7, 30 or 90 days.

The main difference from most unfollower apps is that it never asks for an Instagram login. Instead of signing in as the user and making automated requests on their behalf, which is what breaks Instagram's terms of use and gets accounts restricted, it reads the public follower list from the outside. Nothing connects to the account.

Because Instagram publishes no record of unfollows, they are detected by comparing one scan against the next, so a few scans are needed before the first result appears. New accounts are scanned three times in the first week to shorten that, then settle into a weekly report.

Pricing scales with account size, from 29 USD per month under 5,000 followers up to 129 USD per month at 100,000. Accounts above 100,000 followers are not supported. Public accounts only, since a private follower list cannot be read from the outside. There is a 30-day refund policy.

The same site also offers free tools that require no account: an Instagram engagement rate calculator, an earnings calculator, and a media kit generator.
