I built this after my partner did an inland sailing course in German and I did a windsurfing course in English, and we both found the same gap: what the course covered wasn't quite what the exam actually asked.
Feed in a real exam's question bank once, and every question is tracked individually from there. Nothing generic, nothing you have to assemble yourself first.
The app runs a Leitner spaced-repetition system: get a question right and it moves further out before it resurfaces, get it wrong and it comes straight back for another attempt. Time goes toward the questions you actually don't know yet, not the ones you've already mastered.
Started with a single 300-question German sailing licence exam. A second course, an international windsurfing licence, is already live on the same platform, each tracked completely independently.
