iOS App Signer is an app used for (re)signing iOS apps, which makes the iOS identity it as a trusted app.

What is iOS app signing?

The Apple store includes around 2 million apps, and all those are signed by trusted developers. Apple only supports signed apps and don’t allow even your own app to be used in an iOS device if it is not signed by a trusted developer.

Usually, to sign an app you need to have a paid developer account, which will cost around 99USD per year. Due to this reason individuals who do app development don’t have a way of trying out the apps on iOS devices as they are unable to get signed. But with iOS App Signer it is no longer a problem. It is a free application that runs on Mac which helps you sign and sideload IPA, DEB, APP and xcarchive file formats into iPhones, iPads and even Apple TV.

The complete process of app signing requires other application support such as XCode which we will be taking more in during the process of signing.

How App Signer works

The process is simple, AppSigner helps the developers to bypass the lock which is set for only paid developers. This enables app (re)signing through free developer accounts.
