How Ksign gets the app on your iPhone
Your downloaded IPA sits in Files, and iOS refuses to open it there.
Import it into Ksign straight from Files, no cable needed.
Pick your certificate, and Ksign signs the app right on the phone.
Install it, and the app opens from your home screen.
Two checks before you sign
Answer them in order. Each answer brings you to the part of this page you need.
Do you already have the .ipa file on this iPhone?
Ksign works on a file you hold. It signs and installs it, and it does not find apps for you.
Get the file first
An IPA is the package an iOS app ships in. Download the one you want from its developer or a source you trust, save it to Files, then head back here.
Back to the first checkDo you have a signing certificate to import?
iOS checks every app for a valid signature before it runs. The certificate is what Ksign signs with.
You're set, and here's why it works
It's like a stamp on a letter. iOS only delivers apps that carry a valid stamp. Your certificate is the stamp, and Ksign presses it onto the IPA right on your phone.
What it won't do
Ksign won't sign an app without a certificate. Import one first, a paid one or one you already own, and the Sign button does the rest.
