AltStore Pros and Cons:

These are the main advantages and disadvantages of using AltStore:


  • You do not need to jailbreak to use AltStore
  • Because you are creating and owning your own developer certificates, the apps cannot be revoked by Apple.
  • Works to sideload apps the same way as Cydia Impactor does


  •  You can only have three active apps at any time ( i.e., Altstore + 2 more )
  • You need to use your computer to install AltServer so you can install AltStore on your iOS device. You can enable Wi-Fi Sync on iTunes after, so you get a fully untethered experience.
  • You must do an app refresh every seven days to continue using your apps

Troubleshooting Guide:

  • Dmg cannot be opened

Fixing this is simple and occurs on Mac computers. Open your Mac Downloads folder and open the .dmg file from there.

  • File Installation Failed

You may get one of the following error messages:

  • “Installation Failed; you are not a member of any development team.”
  • “Incorrect Apple ID or Password”
  • “Your development team has reached the maximum number of registered devices.”

No matter which error message it is, you can only fix it in one way. Open and generate an app-specific password. The errors occur because you have enabled two-factor authentication.

  • Could Not Find AltServer 

This occurs when you are refreshing the apps and indicating that AltServer wasn’t found on your Wi-Fi network. Check that you are using the same network; if you are, it indicates that your firewall or the network itself is blocking communication. Try reconfiguring your network, allowing device discovery.

Frequently Asked Questions:

We also get asked quite a few questions about AltStore. Some of these questions are answered below.

  • What is AltStore?

AltStore is an alternative app installer for the iPhone and iPad that doesn’t require a jailbreak. It also does not rely on enterprise developer certificates as other alternative app stores do and, as such, cannot be revoked by Apple.

  • Is AltStore a Jailbreak?

No, AltStore is not a jailbreaking app. AltStore is an installer that allows IPA files to be sideloaded and signed on your device, something that cannot be done with the official app store.

  • How Does AltStore Work?

AltStore app uses a feature the Apple app developers use for testing apps before they go to the Official iOS appstore. The apps are self-signed on your computer rather than using enterprise certificates. However, you are limited to no more than 3 active apps on your device at any given time, 1 of which is reserved by AltStore – that means you can install 2 more apps of your choice.

  • What Apps will I Find in AltStore
  1. GBA4iOS
  2. Delta Emulator
  3. Unc0ver

As you can see, there are few apps available right now, but this number will increase over time. You also have the option of downloading external IPA files and installing them.

  • Can the AltStore Certificate be Revoked?

No. AltStore doesn’t use Enterprise Certificates, so Apple cannot revoke them and shut the apps down like other alternative app stores. Each user “Signs” their own apps with an individual certificate that cannot be revoked.

  • Why is my Apple ID Required while using AltStore?

So long as you have a valid Apple ID, Apple allows you to install any app you have onto your device to “Test” it. This feature was included with AltStore, ensuring your ID communicates with the Apple servers and let you install the apps you want through AltStore.

  • Why Do I Need to Refresh the Apps on Altstore Every 7 Days?

Because the certificates expire every 7 days if you use a free Apple ID. Those with paid developer ID do not face this and it cost $100 per year. This is why AltStore tries to refresh your apps regularly; ensuring you can do this at least once per week stops the certificates from expiring.

  • Is AltServer required to be Running for App Installation or Refresh?

Yes, the AltServer app must be open and running on the same Wi-Fi network that AltStore ensures you can install and refresh your apps on your device. You don’t need it running permanently, though; simply ensure it is active regularly, and your device is connected, and your apps will be refreshed – do this at least once a week to stop the apps expiring.

The easiest way around this is to have AltServer set to run automatically when you log in to your computer. If you are a Windows user, go into your settings and enable Network Connectivity under Sleep Mode.
