📱 The right app

The app to see who unfollowed you — done right

Search for an app to see who unfollowed you on Instagram and you'll find dozens. Most share the same two problems: they want your Instagram password, and they barely work once you've installed them. UnfollowCheck was built to be the opposite — a real, native iOS app that does one job exceptionally well, and never puts your account at risk to do it.

Here's what makes it the right one. It never asks for your password, reading only public follower data, so there's nothing to hack and no login for Instagram to flag. It works automatically: once your username is in, it scans your followers on a schedule and sends a push notification the instant someone unfollows you — no opening the app, no manual refresh. And it's free, with a 4.7-star rating and 120,000+ users. That combination — safe, automatic, free — is rarer than it should be.

More than unfollows

Because it's a full app and not a one-off web check, UnfollowCheck does more than tell you who left. You get your doesn't-follow-back list, your follower history, a home-screen widget, and a watchlist for tracking other profiles — all from the one download, all without a password.

Prefer to check first?

You don't have to install anything to try it. Run the free scan above on any public profile — including your own — and you'll see the kind of data the app delivers. If you just want a one-time answer right now, the who unfollowed me tool gives it to you on the spot; if you want it to keep watching, that's what the app is for.

💬 Frequently asked

The unfollow app, answered

What's the best app to see who unfollowed you on Instagram?

UnfollowCheck is built for exactly this: a native iOS app that tracks who unfollowed you automatically and sends a push notification the moment someone leaves — all without ever asking for your Instagram password. It also shows who doesn't follow you back and tracks your follower history.

Is the app free?

Yes. Seeing who unfollowed you, your unfollowers list, and unfollow alerts are all free in the UnfollowCheck app. There's nothing to pay just to find out who left.

Does the app need my Instagram password?

No — and you should never use an unfollow app that does. UnfollowCheck works only from public follower data and never asks for your login, so there's no risk of your account being banned, shadowbanned, or hacked.

Will the app alert me when someone unfollows me?

Yes. For public accounts under 10,000 followers, the app scans automatically every week and sends a push notification with the person's @username the moment a scan detects an unfollow. Private or larger accounts use a quick manual check.

Is there an app to see who unfollowed you on Android?

UnfollowCheck is a native iOS app today. If you're on Android, you can still run a free scan on the website to check any profile, and join the waitlist for the Android app.

How is this different from web tools that show unfollowers?

Web tools give you a one-time check and forget you the moment you close the tab. A native app keeps watching — automatic weekly scans, instant push alerts, a home-screen widget, and your full unfollowers history, all without a password.

Get the app. Never wonder again.
