There is a free "Personal" license for basic/normal usage and a "Professional" license for advanced usage which cost 7,50 EUR monthly (longer subscriptions are much cheaper). These prices are already very low, because i have to pay other things like components that i use for this app. So i cannot keep up with other Multiposters in pricing unlike IntelligeN is not compare-able to them. Furthermore for me as dev it is very important to be "really" connected to my users, which is very time-consuming but in my opinion the better deal since IntelligeN is indeed very complex.
Maybe you are good to go with the "Personal" license.
