Because Adobe DPS was a big thing in my apprentice I wanted to build and publish an App with it as my Bachelor-Project in Media-Design. Preparing for this I got kind of confused with AEM as replacement for DPS. I read that AEM is quite expensive and I can't afford more than Adobe CC. So can I still use DPS as learnt in my apprentice or do I need to find a other app building solution? Do you know any good alternatives?
