How to see who unfollowed you on Instagram.
The free 2026 way.

Why Instagram hides who unfollowed you

Let's start with the bad news: Instagram will never tell you who unfollowed you. There's no notification, no list, no setting buried somewhere in the app. All you get is a follower count that quietly ticks down, leaving you to wonder who left. This is deliberate — Instagram knows unfollow alerts would create drama, so the information simply isn't there in the app.

But the information does exist — in the difference between your follower list today and your follower list last week. If you knew exactly who was on the list before and who's on it now, the people who disappeared are your unfollowers. Doing that comparison by hand is hopeless past a few hundred followers, because Instagram constantly reshuffles the order. Doing it automatically is the entire job of an unfollower tracker.

Method 1: The manual way (slow, not recommended)

In theory you can screenshot or write down your follower list, wait, and compare it later to spot who's missing. In practice it falls apart immediately: the list reorders every time you open it, big accounts have thousands of names, and you'd have to repeat the whole thing every single week. It's why almost nobody actually does it this way.

Method 2: UnfollowCheck (free, automatic)

The practical answer is to let an app do the comparison for you. UnfollowCheck takes a snapshot of your follower list and re-checks it on a schedule, then shows you the exact @username of anyone who unfollowed you — plus a running list of everyone who doesn't follow you back. Setup takes about 30 seconds:

1. Download UnfollowCheck. Get the free UnfollowCheck app from the App Store. It never asks for your Instagram password.
2. Enter your public @username. Add your public Instagram handle — no password and no login required.
3. Let it take a snapshot. UnfollowCheck records your current follower list as a baseline to compare against later.
4. See who unfollowed you. On each weekly scan, UnfollowCheck compares your follower list to the last one and shows the exact @username of anyone who unfollowed you, with a push notification.

For public accounts under 10,000 followers this runs automatically every week and alerts you the moment someone leaves. If your account is private or has more than 10,000 followers, you use a quick manual check instead — download your Instagram data file and upload it in the app, and it shows your unfollowers instantly.

The one rule: never hand over your password

Whichever tool you use, follow this rule: never give an unfollower app your Instagram password. The apps that ask for your login are exactly the ones that get accounts banned, shadowbanned, or hacked. UnfollowCheck never asks for your password — it works from public data only — which is why 120,000+ people trust it. Once you know who left, you might also want to see who doesn't follow you back or track your followers over time.
