UNFO app icon: a yellow ghost on a black square

Who's really following you?

UNFO reads your Instagram audience and tells you the plain truth about it — who left, who never follows back, and who watches every single story.

What you get

Every question you've
asked about your account.

Who doesn't follow you back

The full list, counted and sorted. Unfollow anyone straight from it, one tap each — only when you tap.

Secret admirers

People who follow you while you don't follow them. The ones you never noticed.

Who left — and when

UNFO keeps a dated record, so "stopped following you" stops being a guess. A person who never followed back isn't the same as one who walked away.

Story viewers

Everyone who watched, who never misses one, and the single most loyal viewer you have.

Ghost followers

Followers who never watch a story and never react — counted from what actually happened, not from a made-up score.

Your best times to post

Windows worked out from when your own audience shows up, not from generic advice.

Ghosty, your assistant

Ask in plain words — "who unfollowed me?", "who watches everything?" — and get an answer read off your real numbers.

One report

Mutuals, admirers, lost followers, ghosts and story viewers, all on a single screen.

How it behaves

The parts most
apps don't tell you.

  • Watching a story through UNFO doesn't mark it as seen. We read the page, we don't run it. The person whose story you opened is not notified.

  • UNFO never acts on its own. It doesn't post, like, comment, follow or unfollow in the background. Something happens only when you tap it.

  • Your lists are built on your device. Followers, admirers, ghosts and story viewers are worked out locally.

  • When you ask Ghosty a question, it needs context. Your counts and up to 20 usernames per list are sent to Google's Gemini model to write that answer — and nothing else. The full detail is in the Privacy Policy.

  • Empty is not the same as zero. If a list can't be filled yet, UNFO says so instead of inventing names or numbers.

See who's really there.
