Any recommendations for apps within health and learning geography?

I’m wondering if anyone here knows about an app that provides world map quizzes? As I think it’s a fun way of freshen up capital city’s and country’s worldwide. Or apps that provide other ways to learn geography?

Also, any recommendations on European alternative on apps related to fitness, diet, health would be really appreciated.

Want to applaud everyone here for this amazing community. I would probably not have discovered DeepL, Ecosia and LeChat hadn’t it been for tired-of-his-name and this group. Planning on opting out of the Google world and more, just have to mentally prepare my self.

Thank you in advance!
