A push notification with the @username the instant a scan finds someone who unfollowed you.
An unfollow tracker that does the watching for you
The point of an unfollow tracker isn't to check who left — it's to never have to check again. Instagram tells you nothing when someone unfollows, so without a tracker you're stuck either obsessively re-counting your followers or simply not knowing. An automatic Instagram unfollow tracker removes the chore entirely: it watches in the background and tells you, instead of the other way around.
That's exactly how UnfollowCheck works. Once you've added your username, it snapshots your follower list and re-checks it on a schedule, comparing every scan to the last. The moment someone disappears, you get a push notification with their @username — no opening the app, no manual refresh. Whether you searched for an “unfollow tracker” or an “Instagram unfollow tracker”, what you want is this: alerts that come to you, automatically.
Automatic for most, manual for the rest
For public accounts under 10,000 followers, tracking is fully hands-off: weekly scans and instant alerts with zero effort. If your account is private or larger, Instagram limits automatic checks, so you use a quick manual check instead — download your Instagram data file and upload it in the app, and your unfollows appear immediately. Either way you end up in the same place: you know who left, without scrolling for it.
Track unfollows the safe way
The unfollow-tracker space is crowded with apps that want your Instagram login — and those are the ones that get accounts banned, shadowbanned, or stolen. UnfollowCheck never asks for your password. It reads only public follower data, so there's nothing to leak and no login for Instagram to flag. That safety is why 120,000+ people trust it. Alongside the tracker you also get the full unfollowers list, a doesn't-follow-back list, and the wider followers tracker.
Want a name right now?
The tracker is built for the long game — set it once and let the alerts roll in. If you just want to find out who unfollowed you this minute, the who-unfollowed-me tool gives you the answer on the spot. Use them together: the tool for now, the tracker for everything after.

Tracking unfollows, answered
What does an Instagram unfollow tracker do?
An unfollow tracker watches your follower list for you and tells you when someone unfollows. UnfollowCheck re-checks on a schedule and sends a push notification the moment a scan detects an unfollow — so you find out automatically instead of constantly checking by hand.
Does it track unfollows automatically?
Yes — that's the whole point. For public accounts under 10,000 followers, UnfollowCheck scans every week with no effort from you and alerts you the instant someone leaves. Private or larger accounts use a quick manual check: upload your Instagram data file and your unfollows appear right away.
Will I get an alert the moment someone unfollows me?
You'll get a push notification as soon as the next scheduled scan detects the unfollow, with the person's @username. It's the closest thing to a real-time unfollow alert that's possible without your password.
Is the unfollow tracker free?
Yes. Automatic unfollow tracking and alerts are free in the UnfollowCheck iOS app. There's nothing to pay just to know when someone unfollows you.
Can I track unfollows without my Instagram password?
Yes, and you never should give your password to an unfollow tracker. UnfollowCheck works only from public follower data and never asks for your login, so there's zero risk of your account being banned or hacked.
Does the person know I'm tracking unfollows?
No. Unfollow tracking is completely private. The person who unfollowed you isn't notified and has no way of knowing you're tracking — you simply get the alert and their @username.
What's the difference between an unfollow tracker and an unfollowers list?
An unfollow tracker is the automatic engine — it watches and alerts. The unfollowers list is the running record of everyone who has left. UnfollowCheck gives you both: continuous tracking plus the full list, in one app.
Never check for unfollows again.
Download UnfollowCheck and let it track unfollows automatically, with instant alerts and your full unfollowers list. Never asks for your password.
