How it works

  • Growth compounds — a steady monthly rate snowballs over time.
  • Enter either a percentage or a flat number of new followers per month.
  • Set a goal to see roughly how many months until you reach it.

Numbers only mean something if the audience is real

Instagram has no public data API, so the free authenticity check can't score it yet — it currently covers YouTube and Twitch. Why →

Frequently asked

What is a good monthly growth rate on Instagram?

Roughly: 10%+/month is fast, 3–10% is healthy, under 3% is slow. Smaller accounts usually grow faster in percentage terms.

Is buying followers a shortcut?

No — bought followers tank your engagement rate and authenticity score, which hurts reach and brand deals. Grow real ones.
