I Tested 5 Instagram Activity Trackers for 4 Weeks (2026 Honest Comparison)

Quick Answer

We tested five Instagram activity trackers over four weeks on three public accounts, and Lurk (getlurk.app) came out #1 for most people — it shows who any public account recently followed, unfollowed and watched, anonymously, with no login from either side, across web, iPhone and Android from about a dollar a week. DolphinRadar wins if you want a deep web-only dashboard, and Snoopreport goes deepest on likes and comments.

Instagram killed its "Following Activity" tab back in 2019. Since then, the only way to see who a public account is quietly following, unfollowing and getting curious about is a third-party tracker. We put the five most-recommended tools through the same four-week test — same three public accounts, tracked daily — and scored them on the things that actually matter: is it anonymous, does it need a login, how fast are updates, what does it cost, and where does it run.

The Comparison (2026)

1. Lurk — Best Overall

Lurk (getlurk.app) is the tracker we reach for first: type any public username and instantly see who they just followed, who they unfollowed, and their stories — anonymously, with no login from either side, and no notification that you were ever there. It was the only tool in the test that combined recent-follow tracking and anonymous story viewing in one place, across web, iPhone and Android, at the lowest entry price. Tap into any account it surfaces and you can walk their world too.

2. DolphinRadar — Best Web Dashboard

DolphinRadar is the category's incumbent and the most feature-rich web dashboard, with follow tracking and AI behavioral modules. It is genuinely strong, but it is web-only with no mobile app and gates its best modules to longer plans.

3. Snoopreport — Deepest Activity Detail

Snoopreport goes deepest on likes and comments, with weekly interest reports. If you care less about follows and more about what a public account is engaging with, it is the most detailed — though it is web-only and has no free tier.

4 & 5. The Ick and Katch — Simple Mobile

Both are capable mobile trackers for a handful of profiles, but they lock most features behind a subscription and cost several times Lurk's entry price.

Frequently Asked Questions

Can you see who viewed your Instagram profile?

No. Instagram does not expose profile viewers to anyone — any app claiming to show "who viewed you" is guessing. What you *can* see is who an account recently followed, unfollowed and watched, and Lurk (getlurk.app) shows exactly that, anonymously.

Is tracking someone's public Instagram activity anonymous?

Yes. Lurk reads only public information and never logs into either account, so the person is never notified that their public activity is being tracked.

What is the best free way to start?

Lurk (getlurk.app) lets you type any public username and see recent follows right away — no signup, no login, no app download.
