KasusKnackerAn app for practicing the most common German grammar topics
Antonio Sanchezstarted a discussion
What part of German grammar do you struggle with most?
I’m building KasusKnacker, a German practice app focused on drills (not lessons). Which topics cause you the most pain: der/die/das, cases, prepositions, conjugation, pronouns…? I’m prioritizing based on real pain points.

Do you prefer guided learning or practice-on-demand?
Many apps force you through a fixed flow of screens/levels. I personally dislike that. KasusKnacker is designed for “open → practice immediately → close”. Which style do you prefer and why?

On my daily job, I often need to search for developers. There are many platforms for that out there, but I wasn't happy with any of them: they were all too expensive or too complicated. I had been looking for months for an idea for a new side project, so I decided to build my own website for searching jobs and developers.
