They offer a lot of free help and support: tutorial videos, articles in their Knowledge Base, Help Screens and lots of other free resources etc. But I found that I didn't actually need most of it cos TimeTabler is just really easy and intuitive to use. It's saved me so many hours since I switched from Nova, it was really quick to export into our MIS too.
I think they still offer a free demo on their site: https://www.timetabler.com/ Hope that helps!
