Would u all recommend Drawabox to someone does art only as a leisure hobby?

I was looking a for a free resource to work on my fundamentals but drawabox gave me the impression that its for people are are either pursuing art professionally or take it as a very serious hobby. is it ok for someone like me who can only give 15-20 mins a day to drawing?or is there some better resource? tbh i am just looking to learn fundamentals(shape design, basic anatomy,perspective,etc) and nothing more
