Hey Product Hunt 👋 I built Judo Academy because my daughter started judo and I wanted a way for her to keep learning between classes — belt terminology, rules, technique names, all the stuff that's hard to absorb only from one hour a week on the mat. What started as a simple quiz for her turned into a full app: a 90-technique library, daily challenges, an AI sensei you can ask judo questions any time, and a training journal. It's still early — I'm a solo developer, and this is very much a labor of love rather than a funded startup. Core features (technique library, daily challenges) are free and unlimited. There's an optional premium tier for people who want unlimited quiz/AI/journal use. Would love feedback from this community, especially if you train (or have kids who train) any martial art — I built this for judo specifically, but a lot of the "how do I remember all this terminology" problem is universal. Thanks for checking it out! 🥋
