You can download apps on iPhone without App Store by sideloading IPA files through tools like AltStore or by using Apple's official TestFlight platform, though you'll need to enable Developer Mode first if your iPhone runs iOS 16 or later. The safest and most legitimate route for most people is TestFlight, which requires no Developer Mode and carries zero security risk, while sideloading via AltStore offers more flexibility but comes with a 7-day signing limit that requires periodic reinstallation. If you want a specific game that isn't on the App Store, you can download master royale on iOS using these same sideloading methods.
What to know before you download apps on iPhone without App Store
Before you attempt any method to download apps on iPhone without App Store, understand that Apple does not vet these apps the way it vets App Store submissions. Apps installed from outside the official store can contain malware, steal your data, or break after an iOS update. You are solely responsible for the safety of anything you install this way. Additionally, if your iPhone runs iOS 16 or later, you must enable Developer Mode before any sideloaded or locally built app will launch, without it, the app will crash immediately. Finally, note that Apple officially supports alternative app marketplaces only in specific regions like the European Union, Brazil, and Japan; for everyone else, sideloading is an unofficial workaround that Apple does not endorse. If you proceed, you may also want to change download settings from Wi-Fi to mobile data iPhone to avoid interruptions when downloading large third-party app files on the go.
Enable developer mode on your iPhone (required for iOS 16+)
Developer Mode is a security gate that Apple introduced with iOS 16 to prevent unauthorized code from running on your device. If you skip this step, every sideloaded app will fail to open, regardless of how carefully you installed it. The toggle is hidden by default, so you must locate it manually.
- Open the Settings app on your iPhone.
- Tap Privacy & Security.
- Scroll down until you see Developer Mode.
- Toggle it to On.
- Tap Restart when prompted, and enter your passcode after the device reboots.
After the restart, Developer Mode remains enabled until you turn it off. You only need to do this once, not per app. If you ever disable it, all sideloaded apps will stop working until you re-enable it.
How to sideload apps using AltStore
AltStore is the most popular non-jailbreak method to download apps on iPhone without App Store because it works entirely through your Apple ID and a companion app on your computer. It does not require a jailbreak, and it supports both Windows and macOS. The core idea is that you sign an IPA file, the app package, with your own Apple ID, then install it directly onto your iPhone. This method is ideal for apps that are not available in the App Store, such as emulators, tweaked apps, or custom utilities.
- Download and install AltServer on your computer from the official AltStore website.
- Connect your iPhone to your computer using a USB cable and unlock the device.
- Launch AltServer and select your iPhone from the menu bar or system tray.
- Choose Install AltStore from the AltServer menu, then enter your Apple ID and password when prompted.
- Wait for AltStore to appear on your iPhone's home screen, then open it.
- Select the IPA file and enter your Apple ID again to sign and install it.
Every app you sideload with AltStore is signed with your Apple ID, which means it expires after seven days. There is no AltStore seven day signing limit workaround without computer, because the signing is tied to Apple's free developer certificate. After seven days, you must reconnect your iPhone to your computer, open AltServer, and reinstall the app to refresh its signature. If you don't, the app will stop launching until you do. Some users keep a spare Lightning cable at their desk just for this weekly refresh.
Trust the developer profile to open your app
This is normal and expected, it is Apple's way of forcing you to explicitly approve the certificate used to sign the app. Without this manual approval, the app will not run, even though it is already on your device.
- Open the Settings app on your iPhone.
- Tap General.
- Scroll down and tap VPN & Device Management.
- Under the Developer App section, tap the profile that matches your Apple ID.
- Tap Trust, then confirm by tapping Trust again in the pop-up.
Once you trust the profile, every app signed with that same Apple ID will launch without further prompts. You only need to do this once per Apple ID, not per app. If you ever delete the profile from this menu, all associated apps will stop working until you trust it again.
Try Apple's official beta testing platform: TestFlight
TestFlight is the only method to download apps on iPhone without App Store that carries zero risk and requires no Developer Mode. It is Apple's official platform for distributing beta versions of apps to testers. Developers send you an invite link via email or a public URL, and you install the beta app directly through the TestFlight app, which you download for free from the App Store. Because Apple hosts the distribution, there is no sideloading, no signing certificates, and no seven-day expiration, beta apps simply work until the testing period ends. If you later need to revert to a stable release, you can also download older versions of apps on iPad through a similar official process.
To use TestFlight, you need to be invited by a developer. Many developers offer public TestFlight links on their websites or social media channels, especially for apps that are still in development. Once you have a link, open it on your iPhone, tap Accept, and TestFlight will handle the installation. The app appears on your home screen with a small orange dot next to its name, indicating it is a beta. You will receive updates automatically through TestFlight, and you can leave the beta program at any time by tapping the app in TestFlight and selecting Stop Testing.
TestFlight is ideal if you want to try a new app before it hits the App Store, or if you need access to a beta version of an app you already use. It is not a solution for downloading apps that are permanently banned from the App Store, because Apple reviews every TestFlight build before it goes live to testers. But for legitimate early access, it is the safest possible route.
A note on official alternative app marketplaces
Apple does allow third-party app marketplaces in certain regions, but this is not a universal solution. As of now, users in the European Union, Brazil, and Japan can install alternative app stores by visiting a developer's website in Safari, tapping an install link, and then approving the installation in Settings under Manage App Installation. These marketplaces can distribute apps that would not pass the standard App Store Review Guidelines, but every app still undergoes Apple's Notarization process, which is a baseline security and privacy check. This means even in supported regions, you are not getting completely unvetted software.
For everyone outside these regions, this option simply does not exist. Your iPhone will not show the Manage App Installation setting, and attempting to visit an alternative marketplace website will result in a message that the installation is not allowed. The only ways to get apps outside the App Store are the sideloading methods described above, or the Apple Developer Enterprise Program, which is reserved for large organizations that need to distribute proprietary internal apps to their employees. If you are an individual user, the Enterprise Program is not available to you. In short, official alternative marketplaces are a regional exception, not a global feature, and they will not help most people who want to download apps on iPhone without App Store.
