I have looked around the community but did not see this anywhere. Does anyone know how to determine if an LTI app is free? I have tried looking at apps with "Open Access" on the EduAppCenter vs those that are authenticated. So it seems that the latter require a consumer key and shared secret - but does that information always cost money, or could that be free?
I have a VoiceThread subscription for my school, but VoiceThread wanted to charge me (yearly!!) for the consumer key and shared secret. It would be helpful to know how to find LTI apps that don't cost anything additional to add.
