AltStore - Sign & Sideload IPAs without Jailbreak

AltStore is an IPA Signing app, that utilizes both your iPhone and a computer to sign third-party IPAs on your iPhone. This app doesn’t install the IPAs directly to your phone, rather you are to use your computer to connect with the AltServer, and then connect your iPhone to the computer to get the task done, which is known as Sideloading!

Most importantly, AltStore doesn’t require you to jailbreak your iPhone. However, AltStore is limited in performance in terms of the number of apps you can run at a given time, which is 3 for the time being, as well as re-signing necessity to keep the installed 3^rd party apps functioning.

However, as per the AltStore team’s tweet in February 2023, it was announced that they are working on removing the three-apps limitation from the AltStore app, by utilizing the MacDirtyCow exploit. If that’s the case, this limitation will be removed only on iOS 14 – iOS 16.1.2, excluding iOS 15.7.3.
