I have tried a number of Learning management Systems:
Learndash, but I have a sort of love /hate relationship with Wordpress.
Heights, beautifully designed with a professional look for clients, But a little bit complicated.
Influencersoft: I bought it last year for a higher price than tier 3 here:-( But they are more focused on their sales than helping customers and updating their product. I kind of regret it)
But what Acadle excels at for me is the ease with which you create a course and lessons. A there are a lot of features. The speed of their support is also high. And integration with 'plugnpaid' and 'pabbly connect' which makes paying in the Netherlands (Ideal/Mollie) easy.
The look and feel could be a bit nicer. But otherwise very satisfied.
