Hi Product Hunt, I'm Nurefşan, the developer behind KimGitti.

Instagram doesn't tell you who unfollowed you, so people install apps for it, and many of those apps ask for your Instagram password in their own form and then log in to your account from their servers. Nearly every article on the topic warns against exactly that. I wanted an app that answers the warning instead of ignoring it.

How KimGitti works:

You log in on Instagram's own page, inside the app. Your password is never seen, sent or stored by us.
Your account is read on your phone, in your own session. Our servers never log in to Instagram; there are no bots or proxies.
The app only reads. It never follows, unfollows, likes or posts.
Requests are paced, and if Instagram starts refusing them, reading stops and isn't retried for hours.

What you get: who left and who joined between updates (by name and date), who doesn't follow you back, mutuals, likes and comments per post, your biggest fans, and a Profile DNA of what your posts are about.

Honest limits:

No third-party app can promise zero risk; Instagram doesn't approve any of them. We wrote down how to judge one: https://kimgitti.com/en/guides/are-unfollower-apps-safe
Your first update is the starting point. Nothing can show unfollows from before it.
Once a day is plenty; checking more often tells you nothing new.

It's available on iOS and Android in English, Turkish and Spanish. KimGitti is independent and not affiliated with Instagram or Meta.

I'd love your feedback, especially on the onboarding and on anything that feels unclear about how your data is handled.
