Having trouble installing the Onside Store app? This page lists common issues and how to resolve them.
If installation is blocked, first check your Apple Account Country/Region. It must be set to an EU country/region or Japan.
Check: Settings > [Your Name] > Media & Purchases > View Account > Country/Region.
I’m in the EU or Japan but I still can’t install the Onside Store.
Update iOS:
EU: iOS 17.6 or later
Japan: iOS 26.2 or later
Go to Settings > General > Software Update.
Confirm physical location: You must be physically located within the EU (excluding the UK) or Japan. A VPN will not bypass this requirement.
Check your Apple Account region: Your Apple Account must be set to an EU country/region or Japan.
Free up storage: Your iPhone might not have enough free space. The Onside Store app is about 100MB, but iOS needs extra space during installation. We recommend at least 2GB free.
Check your internet connection: Try switching between Wi-Fi and mobile data.
Restart your iPhone: Restarting can resolve temporary issues.
If the issue persists, contact support and include your iPhone model, iOS version, and the approximate time you attempted the installation.
The Install button on onside.io doesn’t work.
Use Safari or Chrome: iOS blocks alternative marketplace installation flows in some other browsers.
Clear Safari website data: Clear cache and cookies in Safari.
Try Private Browsing: Open onside.io in a Private tab.
Disable content blockers: If you use ad/content blockers, temporarily disable them for onside.io.
I’m seeing an error when downloading or updating apps (after installation).
Most download/update errors come from internet connectivity issues, insufficient device storage, or the app’s iOS version requirements.
If you previously installed the same app from another source, uninstall it, then download it again from the Onside Store.
I see NSURLError when downloading an app.
Turn off your VPN and try again. VPNs can cause network errors (including NSURLError) during downloads.
FAQs
Why can’t I install Onside on iOS 17.5 or earlier?
In the EU, Apple’s framework for alternative app marketplaces is available on iOS 17.6 and later.
In Japan, alternative app marketplaces are available starting iOS 26.2 under the MSCA.
Onside Store requires the minimum iOS version that supports alternative app marketplaces in your region.
Staying on a recent iOS version also helps ensure you receive Apple’s latest security updates.
How can I be sure the Onside website is official?
The only official Onside website is onside.io.
Always check the domain name in your browser’s address bar. You can also check the website certificate by clicking the padlock icon; it should show “Onside” (or our registered company name) as the verified organization.
Can I download apps from Onside without installing the Onside Store app?
No. To install apps from Onside, you must first install the Onside Store marketplace app on your iPhone.
Can I download apps without creating an Onside account?
Currently, you need an account to download apps.
