AltStore: iOS App Store alternative that doesn’t require jailbreak
altstore.io
altstore.io
So the AltStore server, running on your computer, will sign apps using your personal AppleID and sideload it onto your device. Because of restrictions Apple put specifically to prevent such thing, apps will expire after 7 days.
So your local AltStore server will refresh app signatures and push them onto device to keep them from expiring.
Hacky and vulnerable to Apple's pushback, but interesting!
