If you mainly use DolphinRadar to see who an account follows and unfollows, the Just Spotted does that for free: one public account, checked every week, with no password and no subscription.
DolphinRadar is a paid Instagram activity tracker. It goes beyond follows into likes, comments and AI reports, but there's no real free tier, and each subscription covers one tracked account. If follows and unfollows are what you care about, you don't need to pay for that.
Track follows and unfollows free
Public accounts up to 10,000 followers. No password, nobody notified.

If you need to see which posts an account liked, who comments the most, or longer AI-written reports, DolphinRadar covers more ground. The tracker deliberately sticks to follow activity and keeps it free.
Reviews of paid trackers keep coming back to the same things: paying before seeing anything, subscriptions that are hard to judge, and unclear results. The tracker answers those directly:
| What people complain about | The 2026 way |
|---|---|
| "The app asked for my password, then I got locked out or warned." | Never asks for your password. You only enter their public username. |
| "It was free, then I had to pay to see the list." | Free weekly checks for public accounts up to 10,000 followers. No blurred results. |
| "It stopped refreshing" or "the numbers were wrong." | Exact accounts, not counts. An unfollow and a new follow in the same week both show up. If Instagram returns an incomplete list, we retry in about an hour instead of showing wrong results. |
| "Ads everywhere and a trial that turned into a charge." | No app, no ads, no trial. Nothing to install; checks run on our side. |
| "Will they know?" | Anonymous. Nobody gets notified. |
| "I have to remember to check." | Automatic. We check every week and email you when results are ready. |
