An unfollowers tracker turns a number into names
On its own, your follower count is useless information. It dropped by four — so what? You don't know who left, when, or why. An Instagram unfollowers tracker fixes that by keeping the one thing Instagram refuses to give you: a running list of the actual people who unfollowed you, with names attached. Whether you searched for an “unfollowers tracker”, an “unfollow tracker”, or an “Instagram unfollowers app”, that list is what you're really after.
UnfollowCheck builds that list automatically. It snapshots your followers, compares each new scan to the last, and adds anyone who left to your unfollowers list — with a push notification so you find out the moment it happens, not weeks later. Over time you get something more useful than a single check: a history of who left and when, so you can connect the dots between what you posted and who walked.
Track unfollowers without risking your account
The unfollower-tracking space is full of apps that ask for your Instagram login — and that's exactly how accounts get 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 the whole point, and it's why 120,000+ people use it to track their unfollowers. To find out a specific name fast, the who-unfollowed-me tool gives you the answer in seconds.
Unfollowers, non-followers, and the full picture
An unfollowers tracker is really one half of understanding your audience. The other half is everyone who never followed you back. UnfollowCheck keeps both as separate lists, and rolls them into the wider followers tracker — new followers, ghost followers, and your growth over time. It's the difference between knowing a number moved and understanding exactly what your real, active audience looks like.
Public, private, and large accounts
For public accounts under 10,000 followers, tracking is fully automatic — weekly scans and instant alerts. If your account is private or larger, you use a quick manual check: download your Instagram data file and upload it in the app, and your unfollowers list appears immediately. Either way you get the same result — names, not just numbers — with zero risk to your account.

Tracking unfollowers, answered
What does an Instagram unfollowers tracker do?
It keeps a running list of everyone who unfollowed you. UnfollowCheck records your follower list, re-checks it on a schedule, and flags anyone who leaves — so instead of just watching your count drop, you get the actual @usernames of your unfollowers, updated over time.
Is the unfollowers tracker free?
Yes. You can scan for free, and the UnfollowCheck iOS app gives you your unfollowers list and automatic tracking at no cost. There's nothing to pay just to track who unfollowed you.
Does it track unfollowers automatically?
Yes. For public accounts under 10,000 followers, UnfollowCheck scans every week and sends a push notification the moment a scan detects an unfollow. Private accounts and larger accounts use a quick manual check — upload your Instagram data file and your unfollowers appear instantly.
Can I track unfollowers without my Instagram password?
Yes, and you should never give your password to any unfollower tracker. UnfollowCheck works only from public follower data and never asks for your login, so there's zero risk of your account being banned, shadowbanned, or hacked.
What's the difference between an unfollowers tracker and a followers tracker?
An unfollowers tracker focuses on who left — the running list of people who unfollowed you. A followers tracker is broader: it also shows new followers, who doesn't follow you back, and your follower history over time. UnfollowCheck does both in one app.
Will the people I track know I'm tracking them?
No. Tracking your own unfollowers is completely private — no one gets notified, and the people who unfollowed you have no way of knowing they're on your list.
Can I also track unfollowers for another account?
Yes. With the Spy Watchlist you can add up to 3 public profiles and get a daily report of their follower changes, completely anonymously — useful for keeping an eye on a competitor, a friend, or an ex.
Track every unfollower. Automatically.
Get your running unfollowers list, instant alerts, and a 3-profile watchlist in the UnfollowCheck iOS app. Never asks for your password.
