The answers Instagram hides from you
Who unfollowed you
The exact @username of everyone who used to follow you and quietly left — the list Instagram won't show you.
Who doesn't follow back
The accounts you follow that never followed you in return, in one clean list.
Alerts every time
A push notification the moment someone new unfollows you, so you're never the last to know.
100% private check
Checking is completely anonymous — the other person never finds out you looked.
How to actually find out who unfollowed you
Here's the frustrating truth: Instagram deliberately doesn't tell you who unfollowed you. Your follower count drops, you feel it, and the app gives you nothing — no name, no notification, no list. You're left scrolling your followers trying to remember who used to be there, which is impossible once you're past a handful of people.
An unfollower checker solves it by doing what Instagram won't: it remembers your follower list and compares it over time. The first time you run UnfollowCheck it saves a snapshot; from then on, every time someone leaves, it spots the difference and hands you the exact @username. No guessing, no scrolling — just the answer to “who unfollowed me on Instagram?” in plain sight. If you want the step-by-step version, we wrote a full guide to seeing who unfollowed you.
Find out without risking your account
Plenty of “who unfollowed me” apps exist — and most of them ask you to log in with your Instagram password. Don't. That's exactly how accounts get banned, shadowbanned, or stolen. UnfollowCheck never asks for your password; it reads only public follower data, so there is nothing to leak and no login for Instagram to flag. It's the safest way to find out who left, and it's why 120,000+ people use it.
Stop checking manually — get alerted instead
Finding out once is satisfying. Never wondering again is better. For public accounts under 10,000 followers, UnfollowCheck runs an automatic check every week and sends a push notification the second a scan finds someone who left — so you find out the moment it happens, not weeks later. (Private or larger accounts use a quick manual check: upload your Instagram data file and see your unfollowers instantly.) Either way, you also get the full follower tracker: new followers, your doesn't-follow-back list, and your follower history over time.
Unfollowers vs. people who never followed back
They feel the same but they're different, and it's worth knowing which is which. An unfollower followed you and then left — that's the one that stings. Someone who doesn't follow back never followed you at all, usually an account you follow one-way. UnfollowCheck keeps them as two separate lists, so you always know whether someone left or simply never joined.

Who unfollowed me — answered
Can I really see who unfollowed me on Instagram?
Yes. Instagram doesn't tell you when someone unfollows you, but UnfollowCheck does. It compares your follower list over time and shows you the exact @usernames of everyone who left — something you can't find anywhere inside the Instagram app itself.
Is it free to find out who unfollowed me?
Yes. You can run a free scan to see live follower data, and the UnfollowCheck iOS app gives you your unfollowers list and weekly tracking at no cost. There's nothing to pay just to find out who unfollowed you.
Do I have to give my Instagram password?
No — and you never should to any unfollower app. UnfollowCheck works entirely from public data and never asks for your password, so your account can't be banned, hacked, or shadowbanned. That's the whole reason it's trusted by 120,000+ people.
How soon will I know when someone unfollows me?
For public accounts under 10,000 followers, UnfollowCheck scans automatically every week and sends a push notification the moment a scan finds someone who left. Private accounts and larger accounts use a quick manual check — upload your Instagram data file and see your unfollowers instantly.
Will the person know I checked if they unfollowed me?
Never. Checking who unfollowed you is completely private and anonymous. The other person gets no notification and has no way of knowing you looked — you simply see their @username on your unfollowers list.
What's the difference between unfollowers and people who don't follow back?
An unfollower used to follow you and then left. Someone who doesn't follow back never followed you in the first place — usually an account you follow that didn't follow you in return. UnfollowCheck shows both as separate lists so you always know which is which.
Is this better than other 'who unfollowed me' apps?
Most unfollower apps demand your Instagram login, bury results behind ads, or quietly stop working. UnfollowCheck never asks for a password, sends instant unfollow alerts, keeps your follower history, and is a native iOS app — not a sketchy web tool.
Stop wondering who left. Know.
Get your unfollowers list, weekly tracking, and instant alerts in the UnfollowCheck iOS app. Never asks for your password.
