The short answer
lastfollower
A free scan of your own audience that returns four named lists in about twenty seconds, with no account and no password.
Dolphin Radar
A paid monitoring service that follows one public account you choose and emails you a behavioural report that fills in over weeks.
Pick lastfollower if the question is who unfollowed me. Pick Dolphin Radar if the question is what has that specific person been doing, and you are willing to pay per account and wait for the picture to build.
These two tools get compared a lot because both run in a browser and neither wants your Instagram password. That is where the similarity ends, and the difference matters more than any feature row below.
Dolphin Radar is built to watch one account that is not yours. You name a public profile, pay for it, and the service checks in on it over time until it has enough history to describe that account's habits. lastfollower is built for your own audience. It reads your public follower list, compares it against your last scan, and hands you the names of everyone who left.
Dolphin Radar does sell an unfollower tracker for your own account too, billed separately from the activity tracking. Even there it reports on its own schedule, and if you want to know who unfollowed you this week, a report that refreshes on its schedule rather than yours is not quite the shape of the answer.

Why people move to lastfollower
An answer today, not a picture in a month
Dolphin Radar's value comes from accumulation. It watches an account and refreshes weekly, so the report is thin at first and useful much later. lastfollower gives you totals on your first scan and names on your second, and you choose when the second one happens.
It is pointed at your account, not someone else's
Dolphin Radar answers what has this person been up to. That is a different product from who left me. lastfollower diffs your own follower list against your last snapshot, which is the only way to name an unfollower at all.
You are not billed per account
A Dolphin Radar subscription covers one tracked profile, so watching a second means paying twice. lastfollower has no per-account fee. Scan your main handle, your side project and your business page on the same plan.
Your follower history is yours
lastfollower keeps the snapshot it compares against in your own browser rather than on a server. Clearing this site's data in your browser removes it completely, which is not a request you have to file with anyone.

About Dolphin Radar
Dolphin Radar is a web based Instagram monitoring service. You give it a public username, and it records that profile's following list as a baseline, checks it on a schedule and reports what changes: new follows, unfollows, likes, comments, story engagement and follower count. Reports refresh weekly, with email notifications. It never asks for your Instagram credentials and works only from publicly visible data.
It is genuinely good at what it is for, which is watching one account over a long stretch. It also sells an unfollower tracker for your own account, but as a separate product that reports on its own schedule rather than a scan you run when you want an answer.
Free preview, then paid. Activity tracking is published at $4.49 a month, $10.99 a quarter or $32.99 a year, each covering one tracked account. The unfollower tracker is billed separately: $9.90 for a one-off report, or from $8.90 a month.

lastfollower vs Dolphin Radar FAQ
How is lastfollower different from Dolphin Radar?
Dolphin Radar watches one public account you nominate and builds a behavioural report over weeks. lastfollower scans your own audience and tells you who unfollowed you, who does not follow back, who is new and who has gone quiet, in about twenty seconds. Different question, different tool.
Is lastfollower a good Dolphin Radar alternative?
It is if you were using Dolphin Radar to keep an eye on your own follower count. For that job lastfollower is faster, free to start and not billed per account. If you were using it to monitor somebody else's activity, lastfollower does not do that.
How much does Dolphin Radar cost compared to lastfollower?
Dolphin Radar publishes activity tracking at $4.49 a month, $10.99 a quarter or $32.99 a year, each covering one tracked account, and bills its unfollower tracker separately at $9.90 a report or from $8.90 a month. lastfollower scans free with no account, and Pro is $4.99 a week covering everything you scan.
What is Dolphin Radar following?
It is Dolphin Radar's recent follow tracker. It records a public account's following list when you add it and lists new follows by the day it detects them. Since Instagram stopped ordering following lists by date in September 2026, comparing snapshots like this is the only way any tool can spot new follows.
Do either of them need my Instagram password?
No, and that is one thing they genuinely share. Both read only public data. lastfollower goes one step further by not requiring an account signup before you see your first result.
Can lastfollower track somebody else's account?
No. lastfollower is built around your own audience and the changes in it. If monitoring another person's public activity is what you need, Dolphin Radar is the closer fit.
