Is Scarlet iOS Still Working in 2025? Latest News & Fixes

Scarlet iOS is a well-known app in the iOS sideloading space, allowing users to install third-party apps, modded games, and tweaked applications on iPhones and iPads. However, Apple’s strict security and privacy policies often lead to frequent certificate revocations, causing such apps to stop working.

As we step into 2025, many users want to know:

  • Does Scarlet iOS still work?
  • Can it still bypass Apple’s security restrictions?
  • What are the best ways to fix it if it isn’t working properly?

In this article, we’ll explore the current status of Scarlet iOS, the major issues of installing Scarlet in 2025, and the most effective solutions to keep it running on iPhones and iPads.

Is Scarlet iOS Still Working in 2025?

As of early 2025, Scarlet iOS is still functional on iOS devices, but with some limitations. Here are a few key points:

✅ Scarlet still allows the installation of IPA files.
✅ It remains compatible with iOS 17 and the latest iOS 18.
✅ Users can still sideload apps, but certificate revocations have become a major issue.

However, Apple’s security updates have made sideloading more difficult:

❌ Enterprise certificates are getting revoked faster than before.
❌ Free signing methods (direct installs) have become unreliable.
❌ If Apple enforces stricter policies, Scarlet may stop working in the future.

New Updates and Changes

Scarlet developers have introduced several improvements in the latest updates, primarily focusing on addressing revocation issues to enhance app stability.

Users on iOS 18.3 beta, released by Apple at the end of last year, may experience installation errors. However, EU users can now officially access alternative app stores. Paid certificate services remain the most reliable option, but they are quite expensive.

Conclusion: Scarlet iOS is still working, but new methods are necessary to keep it running.

What Challenges Is Scarlet iOS Facing in 2025?

Apple has introduced major security and privacy enhancements in iOS 18 and later versions, creating challenges for third-party apps. While these updates benefit users in the European Union due to regulatory pressure, they also impose stricter restrictions on sideloading. As a result, Apple has made notable changes to its privacy policies, allowing users in the EU to officially access alternative app stores on their iOS devices.

Apple’s Security Policies and Updates

  • Apple now revokes enterprise certificates within hours, causing Scarlet to stop working.
  • New device verification systems have made sideloading more difficult.
  • Frequent “Untrusted Developer” errors make it harder to install and access external apps.

New Sideloading Restrictions in iOS 18

iOS 18 introduces advanced detection systems that can block third-party apps. But how does this system work?

The operating system automatically verifies whether an app was installed through the App Store or another method. If an app isn’t officially signed or violates Apple’s policies, the system may block it. This system is specifically designed to detect IPA files and unverified certificates, preventing unauthorized installations.

How Does iOS 18 Affect Scarlet and Sideloading?

If you install an IPA using Scarlet or any other third-party tool, iOS 18 may detect it, causing Scarlet or other sideloaded apps to crash before they even open.

Another issue is that if iOS identifies the app, it may permanently disable it.
Apple’s new MDM and certificate verification policies are making sideloading even more challenging.

What Is MDM?

Mobile Device Management (MDM) is a system commonly used by companies and enterprises to manage iPhones and iPads used by their employees. It allows remote control and the ability to impose app restrictions.

What Are the New MDM Policies in iOS 18?

Apple has tightened its verification process for MDM and enterprise certificates. iOS 18 can now automatically detect whether a third-party app, such as Scarlet, is signed with an enterprise certificate. If the certificate is not part of Apple’s official enterprise program, the system may reject it.

Certificate Revocation and Signing Service Issues

Free signing methods, which most Scarlet users rely on for installation, are now getting revoked much faster. However, if you want to install eSign, you can check the complete guide at scarletapps.com.

Many paid signing services have either shut down or become unreliable. As a result, users frequently need to reinstall Scarlet, which causes significant inconvenience.

Despite these challenges, there are still some effective fixes that can help keep Scarlet iOS running smoothly.

Best Fixes for Scarlet iOS Not Working (2025)

If Scarlet iOS isn’t working on your device, try these latest fixes:

1. Using AltStore + Scarlet IPA

Installing Scarlet using AltStore is the most reliable method in 2025.

  1. Install AltStore on your PC (Windows or Mac).
  2. Connect your iPhone and open AltStore.
  3. Download the latest Scarlet IPA file.
  4. Sideload the Scarlet IPA through AltStore and trust it in settings.

Pros: Stable method, no jailbreak required.
Cons: Requires a PC and needs to be re-signed every 7 days.

2. Using Paid Certificate Signing Services

Paid services like Signulous, AppDB, and E-Sign offer a more stable experience.

  • These services require a subscription, usually ranging from $10 to $50 per year.
  • Compared to free methods, they are much more reliable and reduce the chances of certificate revocation.

3. Permanent Installation on Jailbroken Devices

One of the advantages of Scarlet is that it doesn’t require jailbreaking. However, if you’re facing difficulties installing or using it, jailbreaking your device could be an alternative.

If you know how to jailbreak your device properly, consider these methods:

  • TrollStore (for permanent signing)
  • AppSync Unified (for installing unsigned IPAs)

Benefit: No revocation issues.
Drawback: Only works on jailbroken devices, which may lead to security and privacy concerns.

Reinstall Scarlet After Deleting Old Profiles

If Scarlet iOS suddenly stops working, try this fix:

  1. Go to Settings > General > VPN & Device Management.
  2. Delete the Scarlet profile and restart your phone.
  3. Reinstall Scarlet.

This method is effective for fixing minor issues.

Scarlet iOS Alternatives (2025)

If you’re facing issues using Scarlet, here are some good alternatives to consider:

1. AltStore

✅ Signs apps using your Apple ID.
✅ Requires a PC for installation.
✅ More reliable than Scarlet.

2. TrollStore

✅ A permanent sideloading solution.
✅ No need to worry about certificate revocations.
❌ Works only on jailbroken devices and certain iOS versions, but may not support iOS 18 yet.

3. AppDB, Signulous (Paid Signing Services)

✅ Paid platforms that allow you to sign and install apps similar to Scarlet.

What Will Be the Future of Scarlet iOS After 2025?

What’s Next in the Coming Years?

Just like the European Union (EU), other countries might also push Apple to allow sideloading. In fact, Japan has already legalized third-party app stores on Apple and Google devices after passing a law in its parliament.

Scarlet’s developers may find new ways to bypass Apple’s security restrictions. However, Apple could introduce even stricter security measures, making it harder for Scarlet to function in the future.

Will Scarlet iOS Remain Relevant?

If Apple officially allows sideloading, Scarlet could become more stable. However, if security restrictions tighten further, new alternatives will likely emerge.

Conclusion

So, is Scarlet iOS still working in 2025?

Yes, but with some limitations.

  • Apple’s security updates have made sideloading more challenging.
  • Certificates are getting revoked frequently.
  • The best ways to keep Scarlet iOS running are AltStore, paid signing services, and jailbreaking.
