Quick answer: yes. An iOS update does not change how FANS checks Instagram non-followers: FANS still imports Instagram's official JSON export and compares followers and following on your iPhone. Open FANS normally after the update; if you need to import again, select the original intact ZIP from Files.
Apple says data and settings remain unchanged when you update to the latest version of iOS. Still, it is smart to know where your Instagram export is stored before any system update and to keep a device backup for the rest of your iPhone data.
FANS is the best safe solution after an iOS update because it does not need your Instagram password, verification codes, cookies, browser session, server upload, scraping, automation, or live account access. The follower comparison remains on-device.
What an iOS update changes—and what it does not
Apple's official iPhone update guide recommends backing up before updating. A normal software update is different from erasing the iPhone, restoring it, deleting FANS, or moving to a new device.
| Question | Answer |
|---|---|
| Does the update give FANS live Instagram access? | No. FANS still reads only the official export ZIP you choose. |
| Does the update refresh an old export? | No. The ZIP still represents the moment Instagram prepared it. |
| Do you need to request a new export automatically? | No. Reuse the existing ZIP if that snapshot is current enough; request a fresh one when recent changes matter. |
| Does FANS need an Instagram login after the update? | No. The no-login, Files-based workflow stays the same. |
Safe checklist after updating your iPhone
- Open FANS and check that the app launches normally.
- If your previous result is present and current enough, you can keep using it as that export's snapshot.
- If you want to import again, open Files and find the complete original Instagram JSON ZIP.
- Make sure a cloud-stored ZIP is fully downloaded, then select it from inside FANS.
- Keep FANS open until the on-device comparison finishes.
- Request a fresh export through Instagram when you need relationships from after the old export was prepared.
For the full import path, follow how to import Instagram data into FANS. The guide to why FANS uses the Files picker instead of Instagram login explains the safety model.
Keep the trust model unchanged. A software update is never a reason to enter your Instagram password into a follower tracker. Use Instagram's official export and let FANS compare it locally.
If the export ZIP seems missing
First check the location where you saved the file: Downloads, On My iPhone, iCloud Drive, or another Files provider. A cloud icon may mean the archive still needs to download. Do not assume the ZIP was deleted just because it is not in the first folder you open.
If you saved it locally, see how to import from On My iPhone. If Safari handled the download, check the Safari Downloads import guide.
Do not rebuild a missing or incomplete archive. Avoid extracted folders, edited JSON, converted CSV files, and random upload tools. If the original ZIP is unavailable, request and download a fresh JSON export from Instagram.
An iOS update does not update follower data
The date of the iOS update and the date of the Instagram export answer different questions. Updating your iPhone changes system software. It does not ask Instagram for a new follower list, add later follows, or reveal later unfollows inside an older ZIP.
When recent results matter, request a new official export and import that new ZIP. Keep old exports clearly named and private so you do not accidentally choose the wrong snapshot. Learn why results move in why FANS results change after a new Instagram export.
Key takeaways
- You can use FANS normally after a standard iOS update.
- FANS still uses Instagram's official JSON export and on-device processing.
- An iOS update does not make an old Instagram export current.
- If needed, re-import the intact ZIP through Files or request a fresh export.
- Never replace a file problem with a password-based or upload-based tracker.
FAQs
Do I need to import again after every iOS update?
No. Try FANS normally first. Re-import when the app asks you to select a file, when you deliberately want to refresh, or when you need to restore a missing result.
Should I use an old ZIP after updating?
You can if you want the older snapshot. Request a fresh export if you need follows and unfollows that happened after Instagram prepared that ZIP.
What if FANS was deleted instead of updated?
Reinstalling or deleting an app is different from updating iOS. Reinstall FANS from the App Store and re-import an intact official export if needed.
Is FANS free?
FANS is free to download. A Pro subscription is required to reveal the full non-follower list when one exists.
Resume your safe non-follower check
Use Instagram's official export and FANS to compare followers locally after an iOS update—without passwords, uploads, scraping, or automation.
