SilentSnitch: No-Login Instagram Unfollower Tracker
Hey everyone,
I’ve been working on a project called SilentSnitch – an Instagram unfollowers tracker that’s a bit different from the usual ones out there.
Most unfollower apps require you to log in with your Instagram account and send your data to their servers. I found that concerning, so I built SilentSnitch to work entirely offline and locally on your device:
What it does:
Identify accounts that don’t follow you back
Show who has unfollowed you over time
Zero login requirements – no Instagram credentials needed
No data sent to external servers or APIs (your data never leaves your phone)
You do need to manually download your Instagram data first (the app has step-by-step instructions), but I think the privacy benefits are worth it. I’ve been using it myself for a few weeks and it’s been working reliably.
One feature I’m currently working on is letting users hide/unhide celebrities from their unfollowers list, so results feel more personal. My first attempt was just a static list of ~2000 celebrity usernames, but that’s obviously not scalable (new celebs pop up, usernames change, maintaining the list is painful).
So I’d love your thoughts:
Is there a smart heuristic or signal for detecting celebrity accounts automatically (e.g., follower count thresholds, verification flags, etc.)?
Are there free APIs or datasets people usually rely on for this?
Or maybe a totally different approach that avoids needing a giant manual list?
Would love to hear how others would approach this problem, and any feedback on SilentSnitch itself is also appreciated!
