License Terms

for the JACK iOS SDK

Even though JACK is mainly based on GPL & LGPL software components, the iOS version of JACK has been released under revised terms. The exact terms are shown below. The revised license terms were especially necessary to allow commercial third parties to use the JACK iOS SDK, allowing them to link against the static JACK library contained in the SDK. So this especially means:

YES, you can use the iOS JACK SDK for commercial (non-free) apps!
