I've been using jvsg online for a few weeks now, and it's become my go-to for quick vocabulary drills. It helps me practice German sentence structure without the pressure of a classroom setting. The interface is straightforward, and I like that I can track which words I keep forgetting. It's not flashy, but it gets the job done when I have ten minutes to spare.
