If you’ve ever installed third-party apps on your iPhone, you’ve probably seen an error saying “The app is no longer available” or “This app can’t be verified.” This issue is called app revocation and is very common on iOS.
Apple has strict security policies, and when an app is not properly signed or its certificate has been revoked, it stops working immediately. In this guide, you’ll learn what causes revoked apps and how to fix them step by step using safe and legal methods in 2026.
If you’ve ever installed apps outside of the App Store, you may have encountered the “App is no longer available” error. This is caused by certificate revocation, which is common during iOS sideloading.
In this guide, we’ll show you how to easily and safely fix revoked apps on iOS.
What is App Revocation?
App revocation occurs when Apple deactivates the certificate used to sign an app. Once revoked, the app will no longer open on your device.
This usually happens with third-party apps installed using signing tools.
- Common signs of revoked apps
- App crashes immediately upon opening
- “App cannot be verified” message
- App icon turns gray
- Ways to fix revoked apps
- Reinstall the app
The easiest solution is to delete the app and reinstall it using a new certificate.
Steps:
- Delete the revoked app
- Reinstall using your signing tool
- Trust the new certificate
- Use the Airplane Mode trick
This temporary fix should help you open revoked apps.
Steps:
- Turn on Airplane Mode
- Clear Safari data (Settings > Safari)
- Open the app
- Note: This is not a permanent solution.
Use a trusted signing tool
Using trusted tools reduces the chance of revocation.
Popular options include:
- AltStore
- Sideloadly
- Scarlet
Use a paid certificate
Paid signing services provide more stable certificates that are rarely revoked.
What are revoked apps on iOS?
Revoked apps are apps that have stopped working because the developer certificate used by Apple to sign them has been deactivated.
When this happens:
The app won’t open
You may see verification errors
The app may crash immediately
This typically affects:
Third-party apps
Enterprise-signed apps
Apps installed outside of the App Store
Why are apps revoked?
Understanding the cause can help you avoid the problem in the future.
- Certificate revocation
Apple regularly checks enterprise certificates. If misuse is detected, they revoke them.
- Security policies
iOS is designed to block unverified apps to protect user data.
- Expired signing certificates
Some apps simply stop working because their certificate has expired.
- Network Authentication Failure
Sometimes the iOS app cannot be authenticated due to connectivity issues.
Benefits:
Longer app lifespan
Fewer cancellations
Better reliability
How to avoid cancellation
- Avoid installing too many apps
- Use trusted IPA sources
- Don’t share certificates
- Keep apps up to date
Pro tip
Create a secondary Apple ID specifically for signing apps. This helps protect your main account and reduces risk.
Quick fixes for revoked apps:
Reinstall/Reload the sidebar: Delete the app and reinstall it using a different or refreshed certificate. Use Anti-Revocation DNS: Configure DNSCloak with specific blocklists to prevent your device from communicating with Apple’s revocation servers. Clear Safari data: Before reinstalling, clear your browser cache to ensure that the new installation does not conflict with old data. Backup app data: If possible, export the app’s data to avoid losing progress when a certificate is revoked.
Long-term solutions:
Use self-signed certificates. Use AltStore or Sideloadly to sign apps with your own Apple ID, which lasts 7 days but is less likely to cause sudden mass revocations. Developer account: Use a paid Apple Developer account to obtain a 1-year certificate. Disable tracking: If the app allows it, disable “Let apps ask to track you” in Settings > Privacy & Security > Tracking to stop some types of identification.
Conclusion
Canceled apps are a common problem with iOS sideloading, but they can be easily fixed. By reinstalling apps, using better tools, or choosing paid certificates, you can enjoy a smoother experience.
Always prioritize security and use trusted methods.
