I have a license to iStopMotion from MacHeist 2. My kids love the app. They have a Mac at both my house and their Moms house - do they need an additional license for their second computer? They would only ever us it on one or the other. It seems that the App Store version allows 5 installs - what is the license for my version? I have no qualms paying if I need to I just can not seem to figure that out from poking around the various menu options and FAQ’s.
