A follower tracker app that actually keeps watch
Search for an app to track your Instagram followers and you'll find plenty — but most fall into the same traps: they ask for your Instagram password, bury the data behind ads, or simply stop working after a week. UnfollowCheck was built to be the one you keep: a native iOS app that tracks your followers automatically and never puts your account at risk to do it.
The difference an app makes is that it never stops watching. A website gives you a snapshot when you happen to check; the app scans your followers on a schedule and tells you — a push notification the instant someone unfollows, a widget on your home screen, your full follower history building over time. It tracks new followers, unfollowers, and the people who don't follow you back, all in one place.
Free, and never your password
Tracking, alerts, and your non-follower list are all free, and UnfollowCheck never asks for your Instagram password — it reads only public follower data, so there's nothing to hack and no login for Instagram to flag. That's why it has a 4.7-star rating and 120,000+ users. For public accounts under 10,000 followers tracking runs automatically every week; private or larger accounts use a quick manual check by uploading their Instagram data file.
Prefer to see it first?
You don't have to install anything to try it — run the free scan above on any public profile and you'll see the kind of data the app delivers. If you want the full ongoing version with alerts and history, that's the app. You can also compare it against other options on our best Instagram followers app page, or dive straight into the followers tracker.
The tracker app, answered
What's the best app for tracking Instagram followers?
UnfollowCheck is built for it: a native iOS app that automatically tracks your new followers, unfollowers, and the people who don't follow you back — with instant push alerts and a home-screen widget, and without ever asking for your Instagram password.
Is the follower tracker app free?
Yes. Follower tracking, unfollow alerts, and your non-follower list are all free in the UnfollowCheck app. There's nothing to pay to track your followers.
Does the app track followers automatically?
Yes. For public accounts under 10,000 followers it scans every week in the background and notifies you the moment anything changes. Private or larger accounts use a quick manual check by uploading their Instagram data file.
Does the app need my Instagram password?
Never — and you should never use a follower-tracking app that asks for one. UnfollowCheck reads only public follower data, so there's no risk of your account being banned, shadowbanned, or hacked.
What can the app track besides followers?
Alongside new followers and unfollowers, it tracks who doesn't follow you back, your follower history over time, and — with the Spy Watchlist — up to 3 other public profiles, all anonymously.
Is there a follower tracker app for Android?
UnfollowCheck is a native iOS app today. On Android you can still use the free web scan to check any profile, and join the waitlist for the Android app.
Why use an app instead of a website to track followers?
A website gives you a one-time snapshot. The app keeps watching — automatic weekly scans, instant push alerts, a widget, and your full follower history — so you find out about changes the moment they happen, not when you remember to check.
