Fully anonymous

They never see you. No views, no receipts, no trace.

No Instagram login

You never connect your account. Just type a username.

Quiet until it matters

A push when something new turns up. No noise in between.

How it works

Track any public Instagram account in three steps.

1

Add a username

Any public Instagram account. Ten seconds, no login.

2

We keep watch

InstaStalk checks in every few hours and logs what changes.

3

You see everything

Follows, unfollows, and stories in one clean timeline, with alerts for the big stuff.

Stories

Watch stories without them knowing.

Stories play inside InstaStalk, not from your account. No view receipts, no accidental taps, no trace.

Red Flag Score

One number for how it's going.

Every account you watch gets a Red Flag Score from its recent activity. Watch it climb, or calm down.

FAQ

Fair questions.

Is it really anonymous?

Yes. InstaStalk never touches your Instagram account, so there is nothing to trace back to you. Story views happen on our side, not from your profile.

Do I need to log in with Instagram?

No. There is no Instagram login anywhere in the app. You pick a username to watch and we do the rest.

Which accounts can I watch?

Public Instagram accounts. If an account is private, Instagram hides its activity and we cannot see it either.

How fresh is the data?

InstaStalk checks every account a few times a day. Each alert and timeline entry shows when it was spotted.

How much does it cost?

InstaStalk Pro is $8.99 a week or $12.99 a month. It covers up to five watched accounts, stories, and alerts. Cancel anytime in your App Store settings.

Never be the last to know.

Put the accounts you care about on your watchlist and let InstaStalk do the checking.

Requires iOS 17 or later. Works with public Instagram accounts.
