Apps that tell you what's really going on on Instagram.

I'm Knox Devlin. I build small, focused iOS apps around Instagram follow activity: who someone followed last, who unfollowed, and when it happened.

FollowSpy: Follow Tracker iOS

Track any Instagram account's latest follows and unfollows, broken down by who they are, with a full history of changes and alerts the moment something moves.

How I work

Read-only by design: the apps never post, like, follow or message on your behalf. Tracked handles and Instagram IDs stay on your device. Questions about data handling are answered in the Privacy Policy.
