With a computer you can sign your apps without deleting them. You need a computer first to follow the post. We will be using a Windows computer but you can also follow MacOS tutorial on AltStore's website.
Download AltStore from
. If you don't have iTunes and iCloud installed, download the latest version of iTunes and iCloud directly from
(not the Microsoft Store)
Open the .exe and complete the installation.
After installation, open AltStore. Connect your iDevice and it will appear on your "control center" like the image:
Enter your Apple ID credentials (recommended not to use your main account).
If everything is ok, it will install Altstore on your iDevice. Go to your iDevice settings, go to general, profiles and device management and tap on trust.
Now you can import your .ipa's to AltStore and install it without any problems. You might need to enter your Apple ID again.
You can only sign 3 apps (one is AltStore so you can sign only 2 custom apps).
To sign an .ipa just download the file on your iDevice and open in AltStore.
AltStore must be on background on your computer to sign apps.
They expire in 7 days but if you resign using AltStore they won't expire.
