Both Android and iOS require developers to “sign” their apps before they can be distributed and installed. An app is signed with a certificate identifying a developer as the author of that app and verifying the app has not been modified since it was last signed. Apps are self-signed with private certification keys.

App Signing Challenges

The app signing process is compounded, particularly in the enterprise, when you have multiple apps with multiple updates and versions. With iOS apps, things can get more complex with app extensions, entitlements, and multiple distribution provisioning profiles. Without an automated app signing solution, it is a manual process of finding the right credentials and certifying individual apps. It can take weeks waiting on developers to dig up the original information and sign the apps.


Apperian provides an automated app signing solution that guides mobile administrators through the signing process and enables them to sign apps from one location without the assistance of developers. Apps can be deployed in just minutes with a few clicks. (And developers can focus on what they do best: developing apps.)

“Signing apps can add days to our workflow and delay projects — especially considering that iOS apps need to be re-signed annually at a minimum and we’re consistently pushing out updates to our catalogue of in-house apps,” said Ty Rollin, Chief Architect at Mobiquity, Inc. “Now every signing or re-signing can be managed automatically using Auto App Signing and can easily be handled by anyone, saving us a significant amount of time and headaches. Each department now has control to publish their own apps while maintaining the security of our brand’s certificate.”
