Wondering who unfollowed you on Instagram?
There are dozens of apps claiming they can reveal lost followers, identify ghost followers and analyze changes in your audience.
But not every app uses the same data.
Some connect to your Instagram account. Others work with downloaded account information. A third category monitors public follower lists and compares them over time.
The difference matters for privacy, accuracy and what the results actually mean.
We compared seven options based on their publicly documented features, access requirements, pricing and suitability for tracking unfollowers.
Editorial disclosure: ProfileFinder operates one of the services featured in this guide. Rankings are editorial recommendations by use case, not results of a controlled head-to-head accuracy experiment.
Quick Answer: What's the Best Instagram Unfollowers App?
ProfileFinder is a focused browser-based option for monitoring lost followers on supported public accounts without an Instagram password.
FollowBuddy is worth considering if you prefer analyzing an export of your own Instagram information.
DolphinRadar offers a dedicated paid unfollower-monitoring module.
IGDetective combines unfollower information with broader public Instagram activity tracking.
FollowMeter is an established mobile option marketed around account analytics and unfollowers.
FollowSpy offers a broader follower and following tracking package, though its exact unfollower-reporting scope should be verified.
And a spreadsheet remains a free option when complete historical lists are available.
For regular public-account comparisons, use the ProfileFinder Instagram tracker to establish a baseline and review later changes.

2. ProfileFinder — Best for Straightforward Public-Account Unfollower Tracking
ProfileFinder Instagram Unfollowers Tracker is built around comparing complete follower lists.
The first successful analysis records a baseline.
Later regular checks identify profiles that appeared in the earlier list but are no longer present.
What it offers
Lost follower detection
Public-account monitoring
Dashboard reports
Email updates
No Instagram password
Regular snapshot comparisons
It currently supports public accounts with fewer than 30,000 followers.
The advertised price is $9.90 per week for one supported profile.
Advantages
The result is easy to interpret: a follower was present in one complete snapshot and absent from a later one.
The service also doesn't require account credentials.
Limitations
It doesn't reconstruct every historic unfollow and isn't designed for second-by-second monitoring.
Verdict: A focused choice when you want ongoing detection of lost followers on an eligible public account.
3. FollowBuddy — Best for Analyzing Your Own Instagram Export
FollowBuddy offers an alternative workflow using information exported from your own Instagram account.
Its documentation explains how to request follower and following information through Meta Accounts Center and import the downloaded data.
Advantages
You don't need to give the app your Instagram password.
The method works with account information you deliberately export.
This may be appealing to users who want more control over what data they provide.
Limitations
You need to request and supply the relevant export.
Historical unfollow detection still requires a trustworthy comparison basis, and some features require a subscription.
Verdict: Worth considering for people comfortable exporting their own Instagram data.
4. DolphinRadar — Best for a Dedicated Unfollower Monitoring Module
DolphinRadar offers a dedicated unfollower product alongside its broader Instagram activity tools.
Its published support documentation distinguishes one-time relationship analysis from ongoing lost-follower monitoring.
Guardian Mode is the paid option advertised for weekly unfollower monitoring.
As of October 2026, its support pages list Guardian Mode at $12.90 per month, or $8.90 per month with annual billing.
Advantages
DolphinRadar has a dedicated unfollower workflow and supports public-profile analysis.
Its documentation explains that historical monitoring begins from the start of tracking.
Limitations
Different DolphinRadar modules have different prices and capabilities.
A one-time non-follower analysis is not the same as monitoring people who unfollow over time.
Verdict: A relevant competitor for buyers who want weekly public-account unfollower reports.
5. IGDetective — Best for Broader Instagram Activity
IGDetective markets recent follows, unfollows and additional public Instagram activity features.
Its Premium offering starts from $1 per day, billed monthly.
The broader product also includes story-related features and activity history.
Advantages
Users interested in multiple activity categories may prefer its wider feature set.
Limitations
The exact availability of advanced features depends on the plan.
Its broader package may be unnecessary if all you need is a simple list of lost followers.
Verdict: Suitable for people who want more than unfollower tracking.
6. FollowMeter — Best for Mobile Account Analytics
FollowMeter is a mobile app available through major app stores.
Its published listings promote unfollower detection, accounts not following back and broader engagement information.
Advantages
Mobile-first interface.
Combines several types of account analytics.
Available to download for free with optional paid features.
Limitations
Some functionality requires purchases or subscriptions.
The app advertises an account-connected workflow, so you should review its permissions, data practices and billing conditions before use.
Also, claims about "secret admirers" or precise profile viewers should be treated cautiously unless the underlying data source is explained.
Verdict: A possible fit if you want a mobile analytics app and are comfortable evaluating its account access requirements.
7. FollowSpy — Best for Recent-Follow Activity Packages
FollowSpy advertises follower and following lookups alongside other Instagram utilities.
Its Starter plan is currently advertised at $12 per week on the main plans page.
Advantages
The service offers a username-based workflow and plans designed for multiple account checks.
Limitations
Its principal marketing emphasizes recent followers and follows. Buyers specifically seeking a historical list of unfollowers should verify that the exact feature they need is included before subscribing.
Verdict: Consider it when your requirements extend beyond unfollowers alone.
8. Spreadsheet Comparison — Best Fully Free Alternative
If you already have complete historical follower lists, you don't necessarily need an app.
Put the old list in one spreadsheet column and the newer list in another.
Use a comparison formula to identify accounts present before but missing now.
For Google Sheets or Excel:
=IF(COUNTIF(B:B,A2)=0,"UNFOLLOWED","")
This assumes column A contains the old follower list and column B contains the new one.
Advantages
Free and transparent.
No third-party Instagram account connection is required.
Limitations
It requires complete, reliable data.
A spreadsheet cannot recover missing historical snapshots or bypass Instagram's access restrictions.
Which Instagram Unfollowers App Should You Actually Choose?
A good unfollower tool should answer the question you care about without requiring unnecessary account access.
For some people, the most important feature is a free check.
For others, it's continuous monitoring, exportable reports or avoiding Instagram password sharing.
If You Want the Lowest Ongoing Price
DolphinRadar's dedicated Guardian Mode currently advertises monitoring at $12.90 per month or $8.90 per month with annual billing.
That can be considerably less expensive over several months than a weekly subscription.
However, Guardian Mode uses weekly reporting, so compare its update schedule with your own requirements.
See DolphinRadar's official explanation of the differences between its plans.
If You Want Focused Public-Account Tracking
ProfileFinder is designed to detect additions and removals between complete follower snapshots.
Its advertised price is $9.90 per week for one eligible public account, with dashboard and email reporting.
It is a straightforward option, but not automatically the least expensive.
If You Want to Analyze Your Own Exported Data
FollowBuddy takes a different approach by using information exported from your own Instagram account.
That may be preferable if you want greater control over which account data you provide.
If You Only Need to Check One Person
You probably don't need any subscription.
Open your Followers list and search for the username, then verify that you're looking for the correct account.
Our Evaluation Criteria
This comparison prioritizes:
The type of follower information the service analyzes
Whether results come from historical observations
Access to public versus private account information
Pricing and renewal conditions
The number of accounts included
Privacy and login requirements
The practical limitations of the reporting schedule

Editorial disclosure: ProfileFinder offers one of the products discussed. Competing products may be more appropriate depending on price, features and intended use.
9. Unfollowers vs. Not Following Back
This is one of the most important distinctions when choosing an app.
An unfollower is an account that followed you before and later stopped.
Someone not following back is an account you follow that does not currently follow you.
For example, you might follow a celebrity who has never followed you.
That celebrity is a non-follower, not an unfollower.
Some apps advertise both features, but they answer different questions.
If your goal is to find genuine lost followers, choose a service that compares historical follower information.
10. How to Track Unfollowers Without Sharing Your Password
For supported public accounts, ProfileFinder provides a browser-based workflow.
Enter the public username.
Check whether the account is eligible.
Activate the first analysis.
Review changes after later monitoring checks.
Access detected lost followers in your dashboard and email reports.
The first analysis establishes the reference point.
Accounts that leave and return between checks may not be detected.
Frequently Asked Questions
Which Instagram unfollowers app is best?
For public-account monitoring without passwords, ProfileFinder and DolphinRadar are relevant options. For your own exported Instagram data, FollowBuddy uses a different approach.
Is there a free app to see who unfollowed me?
Some apps offer free features, and manual comparison is free if you have complete saved lists. Automated unfollower history often requires a paid feature.
Are Instagram unfollower apps safe?
Safety depends on their data access, privacy practices and permissions. Avoid services that request unnecessary credentials or promise private-account access.
Can you see who unfollowed someone else?
For supported public accounts, list comparison tools can identify follower removals between monitoring snapshots.
Can an app show unfollowers from last year?
Only if suitable historical data exists. New monitoring cannot automatically create a complete past event history.
What does an unfollower app actually detect?
A reliable comparison identifies accounts missing from a later complete follower list that were present earlier.
Are non-followers the same as unfollowers?
No. An account that never followed you isn't necessarily an account that unfollowed.
Can unfollower apps detect private accounts?
Public-data tools cannot override Instagram privacy restrictions.
Do Instagram unfollower apps show exactly when someone left?
Snapshot-based tools can identify the interval between observations. They don't necessarily know the exact moment of an unfollow.
Which app works without Instagram login credentials?
ProfileFinder and several public-account services use username-based monitoring. FollowBuddy works with exported data rather than requiring your Instagram password.
Final Verdict
For one-time checks, begin with free manual methods or your own Instagram information export.
For broader activity tracking, compare IGDetective, FollowBuddy, DolphinRadar and the other options according to your preferred workflow.
If your primary goal is straightforward ongoing monitoring of lost followers on a supported public account, ProfileFinder Instagram Unfollowers Tracker is a focused option worth considering.
Choose based on actual data access and features — not promises of revealing secret activity.
