Katch App Alternative 2026: Same Instagram Follow Alerts at a Fraction of the Price

The best Katch alternative is Lurk (getlurk.app): the same recent-follow tracking, unfollow alerts, and anonymous story viewing Katch is known for, but with a web version you can use right now without installing anything, a free instant check of any public username, and an entry price of about a dollar a week instead of Katch's roughly seven.

---

Katch is a capable mobile tracker. We ran it in our five-tracker test and the core features work: follow tracking, story viewing, push alerts on iOS and Android. People go hunting for an alternative for two reasons, and they are both about friction, not features.

Why people switch from Katch

The price. Katch runs around $6.99 a week and locks most of the good stuff behind that subscription. That is several times what the same tracking costs elsewhere. If you are watching one person out of curiosity, seven dollars every week adds up fast.

No web version. Katch lives on your phone only. There is no way to check from a laptop, and no way to try it on a username before you install an app and start a subscription.

What Lurk does differently

Same category, same anonymity model (no Instagram login from either side, the tracked person never knows). The differences are the browser access, the try-before-you-pay check, and the price.

Try it on your person right now

The honest way to compare trackers is with the account you actually care about. Type their username into Lurk, see who they recently followed in seconds, free, and then decide if you need anything more. If you are comparing the whole category, our tested comparison of 5 trackers and our DolphinRadar review cover the rest of the field.

Common questions

Is Katch a scam?

No. In our testing the tracking worked. The complaints are about price and the subscription lock, not fake data.

Does Katch have a web version?

No, Katch is app-only. If you want to check someone from a browser with nothing installed, that is Lurk's free check.

Can I track someone without them knowing?

With both tools, yes, for public accounts. Neither asks for your Instagram login and the person gets no notification. That is the correct design for this category, and any tool that DOES ask for your Instagram password is the one to avoid.
