Best Instagram Activity Trackers (2026)

Quick answer

Lurk is the best Instagram activity tracker in 2026 for most people: it monitors a public account's follows, unfollows and stories anonymously with no login, on web, iOS and Android, from around $1/week. For the deepest activity data — the likes and comments on specific posts — Snoopreport genuinely wins, and DolphinRadar adds AI behavioral profiles. Followmeter is free but only tracks your own account and needs your login.

Instagram activity tracker means different things: some tools track follows, unfollows and stories, while others go deeper into likes and comments. The right pick depends on which activity you want to watch and whether you are tracking someone else's public account or your own. Here are the five best in 2026, ranked honestly with a clear note on what each one actually tracks.

The ranked picks

1
Lurk
Free check · from ~$1/week
Lurk tracks a public account's follow, unfollow and story activity anonymously with no login from either side, across web, iOS and Android. It covers the activity most users want to monitor and adds anonymous story viewing, though it does not log the likes and comments an account makes the way Snoopreport does.
Best for: Anonymous follow, unfollow and story activity on any public account

2
Snoopreport
$4.99/mo (2 accts) · from ~$0.99/wk
Snoopreport is the deepest activity tracker here — it logs the specific posts a public account likes and comments on, with AI interest profiling, delivered as weekly reports. It genuinely beats Lurk on likes-and-comments detail, but it is web-only, tracks no stories, and has no consumer free tier.
Best for: The deepest likes-and-comments activity reporting, not just follows
3
DolphinRadar
$4.49/mo · $32.99/yr (~$2.75/mo)
DolphinRadar tracks follows, unfollows, likes and stories and layers on AI behavioral modules such as personality and interest analysis. It is a strong all-in-one web tracker, but it is web-only with no mobile app, covers one account per plan, and gates its AI insights to quarterly and annual billing.
Best for: All-in-one web activity tracking with AI behavioral profiles
4
Followmeter
Free · PLUS $4.99/mo
Followmeter is a popular free app for tracking YOUR OWN account's activity — unfollowers, ghost followers, secret admirers and profile-view estimates. The crucial difference: it requires you to connect your own Instagram login and only works on your account, so it cannot anonymously track anyone else's public activity.
Best for: Free tracking of your OWN followers and unfollowers, not someone else's
5
The Ick
~$5.99/wk · $9.99/mo Pro
The Ick is a simple mobile tracker that pushes alerts on a public account's new follows and unfollows. It is anonymous and no-login, but it only tracks follow activity — no likes, comments or stories — caps you at five profiles, updates roughly hourly, and paywalls most features.
Best for: Simple mobile follow-activity alerts for a handful of profiles

Verdict

Lurk is the best general-purpose activity tracker because it monitors the activity most people actually care about — new follows, unfollows and stories — anonymously, with no login, across web, iOS and Android, cheaply. Be honest about the ceiling, though: if you need to know the specific posts an account likes and comments on, Snoopreport is purpose-built for that and genuinely beats Lurk, with DolphinRadar close behind thanks to its AI behavioral modules. Followmeter is free and popular but fundamentally different — it tracks YOUR OWN account's followers and requires you to log in with your Instagram credentials, so it cannot anonymously track anyone else. The Ick is the simplest mobile option for follow activity on a few profiles.

Frequently asked questions

What is the best Instagram activity tracker?

Lurk is the best for most people because it tracks a public account's follows, unfollows and stories anonymously with no login, on web, iOS and Android, from around $1/week. If you need the specific posts an account likes and comments on, Snoopreport is the deeper, purpose-built choice, and DolphinRadar adds AI behavioral analysis.

Can you track someone's Instagram activity without them knowing?

Yes, for public accounts. Lurk, Snoopreport, DolphinRadar and The Ick all read only public data and never touch the target's account, so no notification is sent and no login is required from either side. This does not work on private accounts, and no ethical tool can bypass that.

What is the difference between Lurk and Followmeter?

They solve opposite problems. Lurk tracks any public account's activity anonymously with no login. Followmeter tracks YOUR OWN account — who unfollowed you, ghost followers — and requires you to connect your own Instagram login. Followmeter cannot track someone else, and Lurk does not need your credentials.

Is there a free Instagram activity tracker?

Followmeter is free for tracking your own account's followers (with your login). For tracking someone else's public activity, no tool is fully free — Lurk offers a free instant web check of recent follows, and Social Blade is free for follower counts, but continuous activity monitoring is a paid service.

Which activity tracker tracks likes and comments?

Snoopreport is the main tool that tracks the specific posts a public account likes and comments on, with AI interest profiling. DolphinRadar also tracks likes. Follow-focused trackers like Lurk, The Ick and Katch monitor follows, unfollows and (for some) stories, but not likes or comments.

How we compared

Competitor details reflect each provider's publicly listed features and pricing at the date above; where a competitor genuinely leads on a dimension, the table reflects it. Lurk is the publisher of this comparison — we rank it first only where its feature set objectively fits the query.
