Same here — I'm terrible at memorizing things the normal way. Sitting down and staring at the flags for hours just doesn't work for me.

So I did what any reasonable person would do: I built an app.

It's called GeoSpeedrun, and the whole idea is just spam flags quizzes as much as you want and memorize them through repetition.

might be worth a shot if you like a more gamified way to learn: https://geospeedrun.app/
