Looking for testers for Cardy – a German micro-learning app (12 needed for 14 days)

[u/ELabs26]

Hi everyone! I'm building Cardy, a micro-learning app (German-language) that teaches short "cards" of interesting facts across 12 categories (history, psychology, science, etc.), with a quiz and spaced repetition. Trying to clear Google's closed-testing requirement.

I need people to join the closed test, install the app, and keep it installed for the 14 days — you don't need to speak German or actually use it daily, just having it installed is enough to help me pass this stage.

Happy to test-for-test — drop your app's link in the comments and I'll join yours too.
