v0.21.0
What's new
Recent improvements and changes to Unfollow Checker.
- v0.21.0
Additional lists and username changes
- NewThe "Fans" list shows followers you do not follow back. It supports search, sorting, and CSV export.
- New"Lists from the archive" includes pending follow requests, Close Friends, Favorites, restricted and blocked accounts, hidden stories, accounts you recently unfollowed, recent sent requests, received requests, and removed suggestions. Each list requires the corresponding data in the export.
- NewThe "Renamed" list shows username changes between two archives. A matching account ID confirms a rename and excludes it from unfollows and new followers. Matching follow timestamps alone indicate a possible rename and leave those totals unchanged; not every export includes IDs.
- NewTabs belonging to the same account after a username change can be merged while preserving exports and history, and the merge can be undone. A merged account uses one slot in the three-account limit; with synchronization enabled, the merge is restored on another device.
- ImprovedResult filters can show only renamed profiles or hide them, including possible renames. Filtering does not change the comparison totals.
- ImprovedAdditional lists are recognized in HTML archives with translated field labels. Reimporting the same archive can add previously missing lists to its saved result.
- FixedMissing, unreadable, or detectably incomplete additional lists are marked as unavailable rather than empty. Instagram and Threads data remain separate, including in archives repackaged as ZIP files.
- FixedImporting an older archive and restoring saved data preserve chronological comparison order. An older export does not replace a newer current result, and previous checks remain in the history.
- v0.20.0
Instagram tools, imports, and feedback
- NewInstagram Grid Maker splits a photo into 3, 6, or 9 posts or a carousel of 2–10 slides. It provides cropping, a posting-order preview, and JPG, PNG, or ZIP downloads. Images are processed in the browser without registration or watermarks.
- NewInstagram Font Generator offers 65 text styles for bios, display names, and captions, with previews, categories, favorites, and copying. Conversion runs in the browser; styles use Unicode characters, and unsupported letters retain their original form.
- NewThe archive owner can also be identified from data inside the export, and the pencil button lets you edit an account tab’s label. Editing the label does not change the profile’s username on Instagram or Threads.
- NewThe results page lets you leave feedback or report an inaccurate analysis with the issue and export period. You can optionally include a reply email and a ZIP archive for investigation; submitting an attached archive sends that file to the support team.
- ImprovedA new ZIP archive can be dropped onto the results page or selected with the upload button. A drop area appears while dragging the file.
- ImprovedExport history shows the HTML or JSON format. Results display a warning when the export period is limited, differs between archives, or cannot be verified; analysis continues, and the warning can be dismissed.
- FixedUnfollowed and new-follower lists restore more reliably after reloading and account synchronization. If an older record contains only counts, missing details are marked as unavailable; reimport the original archives to recreate them.
- FixedExports containing a present but empty followers list are handled correctly. If the required following list is missing, analysis shows an error instead of a misleading empty result.
- v0.19.0
Profile previews, filters, and account improvements
- NewThe eye button beside a username opens an Instagram profile preview directly from the list, including on mobile. If Instagram cannot display the preview, a link opens the profile on Instagram.
- NewYou can manually mark a profile as unavailable and remove it from the lists with the "Hide unavailable profiles" filter. Marks are saved only in this browser and can be removed at any time.
- NewSign in or create an account with a six-digit email code. The account security page lets you review active sessions and end sessions on other devices.
- ImprovedWhen switching accounts, you can choose the account’s saved data or the exports on this device. Replacing the data saved in the account requires a separate confirmation.
- ImprovedThe account menu links to saved results and the account page. Light, dark, and system themes each have their own icon, with a mark showing the current choice.
- ImprovedWhile the results page starts, it shows a dashboard-shaped preview instead of a blank screen. The JSON, HTML and ZIP badges in the upload area now open the file picker too.
- ImprovedAll 14 blog articles now have cover images, and the "Read next" section shows full article cards. The About page now introduces the three-person team and credits the articles to their author.
- FixedFollow-back results are more reliable: incomplete follower-list parts no longer produce a misleading result, account-name variants are matched consistently, and a stale comparison is not shown after restoring from an account.
- FixedA saved light theme no longer flashes dark while the page opens, and an accepted cookie banner does not reappear. Settings changed at the same time are saved without losing either update.
- v0.18.0
Export to CSV
- NewAn "Export CSV" button in the results panel, beside search and sort: it downloads the active list — "Not back", "Unfollowed", "New", "Followers", "Following" or "Mutual" — as a CSV file in the current sort order. The search box does not affect the file: it holds as many rows as the counter above the list shows.
- NewThe file columns are username, profile link, follow date and you_follow — whether the archive owner follows that account. The file is UTF-8 with a byte-order mark, so Excel, Numbers and Google Sheets open it without garbled characters. The file name carries the account, the platform, the category and the export date, for example unfollowchecker-name-instagram-unfollowed-2026-09-05.csv.
- NewWhile a past check from the "Export history" is open, the file holds only the username, the profile link and the follow date: the you_follow column is absent, because the answer for that date is unknown.
- v0.17.0
Small improvements and fixes
- ImprovedThe "+" beside the account tabs opens the file picker directly, without a trip to the home page.
- ImprovedThe browser tab of the results screen is titled "Your results · Unfollow Checker".
- FixedThe analysis error message appears in the visible part of the page, and the page scrolls to it.
- FixedChoosing "Load my data" in the "Another account’s data" warning keeps the results screen open instead of returning to the home page.
- v0.16.0
The results at their own address
- NewThe results open at their own address, /results, which can be bookmarked; the home page stays the upload page, and the "Your saved results" card with the date of the last export leads to them.
- ImprovedThe browser’s Back button returns from the results to the upload page.
- ImprovedThe "Save these exports to your account?" question and the "Another account’s data" warning are shown as dialogs on any page, including the results screen after returning from the Google sign-in.
- FixedAfter the account is deleted, signing in again with the same Google account offers to save the device’s exports instead of showing the "Another account’s data" warning.
- v0.15.0
Several accounts and the export history
- NewAccount tabs above the results: exports of different accounts (by the username in the file name) are kept separately, and each account opens in its own tab; the Instagram and Threads exports of one username form a single tab. An archive of another account adds a tab instead of replacing the previous account.
- NewThe "+" beside the tabs adds an account; its hint explains that another account’s export opens in its own tab. The limit is three accounts, and at the limit the button shows an explanation instead of an upload.
- NewThe ✕ on a tab removes the account together with its baseline archives, chart history and export log; the confirmation states what is deleted, from the device and, when signed in, from the Google account as well.
- NewAn "Export history" card in the results side column, available without an account: one row per export with the follower and unfollow counts, newest first; any row can be removed.
- NewA history row opens that check: the "Unfollowed you" and "New followers" lists show who left and who joined between that export and the previous one, and the summary card and the chart marker show the same moment. The "Back to current" button returns to the latest results; details are kept for checks made after this update.
- NewA new archive is uploaded from the results screen with the "Upload a new file" button in the side column; the analysis progress is shown there as well.
- NewAfter the first sign-in, the app asks whether to save the exports already on the device to the account; the "Keep them on this device only" answer is remembered, and uploads from the device are turned on and off on the account page.
- ImprovedThe reference point does not move: the first uploaded archive stays the baseline, and every later comparison is measured against it. The "Set as baseline" button has been removed.
- ImprovedA failed sync shows the reason and a "Retry" button.
- ImprovedThe "Saved locally" badge and the "Clear" button sit on the "Done" title line.
- ImprovedThe account keeps up to 50 latest exports per account and platform; older ones are removed from the account automatically, and the copy on the device is not limited.
- FixedIn Hebrew, the page on mobile opens without a sideways shift.
- v0.14.0
Russian, the account page and export removal
- NewThe interface and the blog are available in Russian, the twelfth language.
- NewThe "Your account" page opens from the account menu with "Manage account": the profile, the full list of exports saved to the account, sign-out and account deletion. The header menu shows up to six latest exports.
- NewExports are removed from the account one at a time; removing the baseline archive shows a warning that the next upload will have nothing to compare against.
- NewSigning out offers a choice: "Sign out, keep them" leaves the exports on the device, "Sign out and remove" removes them together with the session; the copy in the account is kept either way.
- NewIf the device still holds another account’s data, sign-in stops with the "Another account’s data" warning and the choice "Load my data" (the device is cleared) or "Sign out"; the data of two accounts is not merged.
- ImprovedA feedback form completed while signed in is not shown again on other devices of the same account.
- FixedAn archive analysed before signing in appears in the account’s export list after sign-in.
- FixedA confirmed reverse comparison ("Yes, compare" for a file older than the saved one) keeps its result: the older export’s point on the chart and both rows in the history.
- FixedOn short windows the account menu scrolls within itself instead of running past the bottom edge of the screen.
- v0.13.0
A Google account and restore on another device
- NewOptional sign-in with Google: the analysis result is saved to the account and restored on another device. The archive itself is not uploaded, only the parsed result: the follower and following lists, counts and export dates.
- NewAn account menu in the header: the "Sign in" button, the sync state ("Saved to your account", "Saving to your account…"), the list of saved exports, sign-out and account deletion.
- ImprovedThe "Clear" button deletes the result from both the device and the account, so the next sign-in does not restore what was deleted.
- ImprovedThe privacy policy gains a section on the account and the cloud copy: what is stored in the account, who processes it and how to erase everything.
- ImprovedOn mobile, the "Install" button and the theme switch ("Dark" / "Light") sit in the burger menu.
- v0.12.1
Interface text after a site update
- FixedAfter a site update, a page no longer shows internal string names instead of the interface text.
- FixedThe installed app opens offline in the selected language.
- v0.12.0
Traditional Chinese
- NewThe interface, the blog and every page are available in Traditional Chinese, the eleventh language.
- FixedThe FAQ link in the site header carries the same translated label as the one in the footer.
- v0.11.0
Six result lists and a two-column arrangement
- NewThe "Followers", "Following" and "Mutual" figures in the summary card open the corresponding lists; the total number of result categories is six.
- NewThe summary card contains a separate row with the "Not back", "Unfollowed" and "New" figures, together with an indicator of the net change in followers over the period.
- NewSelecting the username in a list row copies it to the clipboard.
- NewThe "Unfollowed" and "Not back" lists carry a note: an account may have changed its username instead of unfollowing, and a link to a previous username does not open a profile.
- NewA back-to-top button is available on the results screen and on the document pages.
- ImprovedOn wide screens the results are arranged in two columns; the site header remains visible while scrolling.
- ImprovedFurther portions of long lists load while scrolling; the "Show more" button has been removed.
- ImprovedAn account profile opens from any area of the row, not only from the link button.
- ImprovedThe demo mode reproduces the full composition of the results screen: the dynamics chart, the two-column arrangement, the lists from the summary card, and an account with more than 200 followers.
- ImprovedSelecting the "Done" heading opens the explanation about the baseline archive.
- ImprovedThe page background gains three moving highlight elements, with reduced brightness on mobile screens.
- FixedSelecting the header logo on the home page returns to the file upload screen.
- FixedThe demo-mode banner is hidden once an archive has been uploaded.
- v0.10.0
Export dates and repeated uploads
- NewHiding an account for the first time shows a note: hiding removes the row from the list only and does not unfollow the account on Instagram or Threads.
- FixedThe period the results cover is taken from the export creation date, not from the file date on the device.
- FixedUploading an export already saved as the baseline shows an explanation instead of returning to the previous results without notice.
- ImprovedThat explanation states the creation date of the saved archive and provides a button to return to file selection.
- ImprovedAdded a warning that Meta names an archive by the download date, not the export creation date.
- v0.9.0
Ten languages, feedback, and fixes
- NewThe interface is available in ten languages: English, Ukrainian, German, Spanish, Portuguese, Turkish, Indonesian, Thai, Hindi, and Hebrew, with right-to-left support.
- NewA feedback form is available on the results page, including for reports about what did not work.
- NewSupport for the standalone Threads export: an archive that contains Threads data only is recognized.
- NewHandled accounts can be hidden in any list, not only in "Not following back"; each list remembers its own hidden rows separately.
- ImprovedThe page opens faster, particularly on mobile.
- ImprovedThe Instagram tab explains the absence of its data in an archive the same way the Threads tab does.
- FixedThe Cancel button stops processing an archive at any stage.
- FixedSelecting the same file again is processed instead of being ignored.
- FixedThe "mutual" badge no longer appears on new followers who are not followed back.
- FixedThe check history saves more reliably, even if the browser is busy or storage does not open on the first try.
- FixedHTML exports with threads.com links are recognized.
- FixedSmall list glitches: the avatar letter for names with special characters, and a stray date line when the follow time is unknown.
- FixedThe contact form: its check loads more reliably and it no longer loses the message topic.
- v0.8.0
Threads, HTML exports, and clearer errors
- NewMeta exports can be uploaded in HTML format, not only JSON; either of the two formats works.
- NewWhen only one of the two archives has Threads data, the Threads tab shows an explanation and the next steps instead of an empty screen.
- NewThe account an export belongs to is shown, and comparing archives from two different accounts raises a warning.
- ImprovedClearer messages when an archive is the wrong file or is missing data: the message states what to fix.
- FixedThe Threads tab no longer mirrors the Instagram list when an export has no Threads data, and instead reports that there is no Threads data.
- v0.7.0
A clearer first step
- ImprovedAfter the first upload, an explanation states why a single archive cannot show unfollows and what to do next.
- FixedA clear error when an archive has no followers list — instead of a confusing empty result.
- v0.6.0
Installable as an app
- NewUnfollow Checker can be installed as an app (PWA) and works offline.
- v0.5.0
Tracking unfollows period by period
- NewA "Set as baseline" control makes the current archive the reference point: the next, newer archive is compared against it and shows who unfollowed in that period. Repeating this step tracks unfollows step by step.
