Looks pretty solid, but I can't say I understand what "themes" are and what the value of them are. Could just be a messaging thing.<p>I would check out Headspace's UI. There is plenty I don't like about it, but what I do like is that it has a very linear, single path forward progression. If I want to unlock all of the other content and see what else I could be learning, I have to complete the introductory level onboarding. It worked very well to build the base habit of meditating with a small ask (10 minutes), and then built on top of that once you get momentum.
