Scarlet iOS Latest Version: Check Yours and Fix Failed Updates
Scarlet iOS is not distributed through the App Store, so it never updates itself in the background. The step-by-step update, from Safari on your iPhone, is in our guide on how to update Scarlet iOS. This page covers the questions around it: how to see which version you have, why new builds come out, what changes between versions, and what to do when an update fails.
How to Check Which Version of Scarlet You Have
- Open Settings on your iPhone or iPad.
- Go to General, then iPhone Storage (iPad Storage on an iPad).
- Wait for the list to load and tap Scarlet. The version number is shown under the app name.
Some Scarlet builds also show the version inside the app, usually in its settings; menu names differ between versions. Installing from the official site always gives you the version offered at that moment, so you do not need to compare numbers before updating.
Why Keeping Scarlet iOS Updated Matters
Like any software, Scarlet iOS receives updates that fix bugs, improve performance, expand the app library, and, most importantly, replace the enterprise certificate used to sign the app. After a revocation, running an outdated copy of Scarlet iOS is a common reason for sudden app failures, certificate trust errors, or crashes.
The Scarlet iOS team releases updates when they are needed, for example after Apple revokes a certificate or releases a new iOS version; there is no published schedule.
What Changes Between Versions?
Each Scarlet iOS update typically includes a combination of the following:
- Certificate rotation: A newly signed build after Apple revokes the old certificate.
- Library additions: New IPA files added to the built-in app catalog.
- iOS compatibility patches: Fixes for issues introduced by Apple’s own iOS updates.
- Bug fixes: Resolved crashes, installation failures and repository sync errors.
Where Scarlet publishes release notes, look on the official website.
Troubleshooting Failed Updates
Update Downloads But Does Not Install
If the new version downloads but the installation stalls or fails, the new certificate is usually not trusted yet. Go to Settings → General → VPN & Device Management and trust the developer associated with the new Scarlet iOS build. See the detailed walkthrough in how to trust enterprise developer certificates on iPhone.
App Shows the Same Version After Update
Check the version again in iPhone Storage as described above. If it still shows the old number, force-close Scarlet iOS by swiping it away in the app switcher, then install again. If nothing changes, do a clean reinstall as described below.
Update Server Is Unreachable
Right after a certificate revocation or a major iOS release, the install can fail while a new certificate is being prepared or many people are installing at once. Wait fifteen to thirty minutes and try again. If the issue persists beyond an hour, check the Scarlet iOS community or official social channels for status announcements.

Last Resort: Reinstalling from the Official Website
If installing over your existing copy keeps failing, a clean reinstall directly from the official Scarlet iOS website is the most reliable path forward. Deleting an app on iOS also deletes its data, so you may need to add your repositories and settings again; try the normal update first, and see how to reinstall Scarlet iOS without losing data.
Steps for a Clean Reinstall
- Press and hold the Scarlet iOS icon on your home screen until the context menu appears.
- Tap Remove App, then confirm by tapping Delete App.
- Go to Settings → General → VPN & Device Management.
- Check that the Scarlet iOS developer entry is gone: enterprise apps have no Remove Management button, and the entry disappears once the apps are deleted.
- Restart your iPhone (power off, then back on).
- Open Safari and navigate to the official Scarlet iOS website.
- Tap the install button and follow the standard installation steps.
This gives you the currently signed build regardless of what version you were running before.
How Often Should You Update?
If Scarlet and your apps open normally, there is no need to reinstall just in case. Update when Scarlet stops opening after a revocation, after a major iOS update, or when installs fail for every app. If you use many repositories, note your repository list before a reinstall in case it needs to be re-entered.
Get the Latest Version
Keeping Scarlet iOS current is the most important thing you can do to keep sideloading working on your iPhone or iPad. Visit Scarlet iOS to get the latest version, and follow the update steps. You can also start from our Scarlet iOS install page in Safari.
