I was wondering: do I need an distribution certificate for my app, when I distribute it through HockeyApp?
I can't find any information about this.
Cheers.
You need an Ad-Hoc
provisioning profile and a matching certificate.
See this Apple documentation with the section "Distributing Your App Using Ad Hoc Provisioning": https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppDistributionGuide/TestingYouriOSApp/TestingYouriOSApp.html
