iPhone Sideloading Limits: Apple Account & Device Rules
Sideloading on multiple iPhones is capped by Apple’s account and device limits: you can install apps from outside the App Store on up to 3 devices per Apple Account, with a 7-day refresh window and a maximum of 3 active third-party app marketplaces per region. This article explains exactly what those numbers mean, how the system tracks your devices, and what happens when you hit a limit.
Background: Why Apple Has Sideloading Limits
Apple introduced sideloading (installing apps outside the App Store) in the European Union under the Digital Markets Act, starting with iOS 17.4 in early 2024. To comply with the law while keeping some control over security, Apple built a system that ties sideloaded apps to your Apple Account, not just to the device. This account-based tracking is what creates the limits you hear about.
The limits exist to prevent abuse of the system—like one person installing a marketplace on hundreds of devices—and to give Apple a way to revoke access if an app or marketplace is found to be malicious. The rules are set by Apple and can change with iOS updates, so always check the latest Apple support pages for current numbers.
How It Works: Account and Device Tracking
When you sideload an app or install a third-party app marketplace, iOS records that action against your Apple Account. Here’s the core system:
- 3 devices per Apple Account: You can have sideloading enabled on up to three iPhones (or iPads) at the same time. This counts devices, not installations—so if you install apps on the same iPhone, it still counts as one device.
- 7-day refresh: Sideloaded apps must “check in� with their marketplace or developer at least once every 7 days. If you don’t open the app or the marketplace, it stops working until you refresh it (usually by opening the marketplace again).
- 3 active marketplaces: You can have up to three third-party app marketplaces installed at once. If you try to install a fourth, you’ll have to delete one first.
Apple identifies a device by its hardware identifiers (like UDID) and associates it with your Apple Account when you first enable sideloading on that device. Removing an app does not immediately free up a device slot—you may need to disable sideloading in Settings or wait for Apple’s system to update.
How to Choose: Managing Your Device Slots
If you have more than three iPhones (or an iPhone and two iPads), you need to decide which ones get sideloading. Consider:
- Primary phone: Keep sideloading on your daily driver.
- Test device: Use a spare iPhone for trying new apps or marketplaces.
- Family device: If you share a device with a family member, remember that sideloading is tied to your account, not theirs.
To free up a slot, go to Settings > General > VPN & Device Management (or the specific sideloading section in EU) and remove the device or disable sideloading. Apple’s servers may take a few minutes to update your count.
Common Problems and Misconceptions
“I deleted the app, why can’t I sideload on another phone?� Deleting an app doesn’t remove the device from your account’s sideloading list. You must disable sideloading for that device in Settings, or wait for Apple’s automatic cleanup (which can take days).
“Does the 7-day refresh mean I need to open the app every day?� No—only once every 7 days. If you open the app itself, it usually refreshes. If you don’t, the app becomes unopenable until you launch its marketplace or developer app to re-verify.
“Can I use the same Apple Account on 10 iPhones and sideload on all of them?� No. The 3-device limit is per Apple Account, not per iPhone model. Using the same account on more than three devices means you’ll have to choose which three get sideloading.
Comparisons: Sideloading vs. App Store vs. AltStore
Apple’s sideloading is different from other installation methods you may have heard about:
- App Store: No device limits, but apps are reviewed and sandboxed more strictly. No 7-day refresh.
- AltStore / third-party marketplaces: These are the official sideloading channels in the EU. They use the same account limits as any sideloaded app.
- Jailbreak: Removes most limits, but voids warranty and is not supported by Apple. Not recommended for security reasons.
The key difference: sideloading is officially supported in the EU, while jailbreaking is not. The 3-device limit applies only to the official sideloading system.
Safety and Security Considerations
Sideloading bypasses Apple’s App Store review, so you’re relying on the marketplace developer’s checks. Before installing anything:
- Only use marketplaces from known developers (like AltStore, SetApp, or Epic Games Store).
- Check that the marketplace itself is signed by Apple (you’ll see a “Verified Developer� notice).
- Be aware that sideloaded apps can request more permissions than App Store apps—review them carefully.
Apple can revoke a developer’s certificate if an app is found malicious, which will make that app stop working on your device until you remove it. This is a safety net, not a guarantee.
Alternatives to Sideloading
If the 3-device limit is a problem, consider these alternatives:
- Use the App Store: Most apps are available there, with no device limits.
- Web apps: Many services offer web versions that work in Safari without installation.
- TestFlight: For beta apps, TestFlight allows up to 10,000 testers per app, but you still need an invite from the developer.
- Multiple Apple Accounts: You could create a second Apple Account for a test device, but that may violate Apple’s terms if used to bypass limits.
Frequently Asked Questions
Can I sideload on an iPhone in the US? No—sideloading is only available in the European Union (EU) as of iOS 17.4. If you’re outside the EU, you can’t enable it in Settings.
Does the 3-device limit include iPads? Yes, iPads count as devices. If you have an iPhone and an iPad, that’s two of your three slots.
What happens if I hit the 7-day refresh limit? The app becomes unopenable. You’ll see a message saying the app needs to be re-verified. Open the marketplace it came from, and it will refresh automatically.
Can I remove a device from my account remotely? Yes, you can go to appleid.apple.com, sign in, and manage your devices. However, removing a device from your account doesn’t always immediately free up a sideloading slot—you may need to wait.
Does factory resetting an iPhone free up a slot? Not automatically. The device is still associated with your Apple Account until you sign out of iCloud and disable sideloading in Settings.
Are there any costs to sideloading? Sideloading itself is free, but some marketplaces charge for apps or require a developer account to install certain apps (like AltStore’s paid tier). Apple doesn’t charge for the feature.
