Dutch learning app

I wanted a better way to learn Dutch phrases and grammar, so I built one. Every word and rule has an Elo rating, like in chess, and the app adapts to what I’m ready to learn next. It brings back words just before I’m likely to forget them. I built it with a backend developer friend, and now I use it every day.
