Hey Product Hunt, Markus here, maker of Kortscore. Quick question for anyone who plays tennis or padel: how often do you stand at the baseline and argue whether it's 40:30 or 30:40? It happened to me often enough that it started to annoy me. Phones stay in the bag, nobody wants to carry a scorecard, and by the third set nobody remembers anything. So I built the thing I wanted on my own wrist. Kortscore is a Wear OS app for racket sports. You tap once per point on your watch, that's it. The watch keeps score, you keep playing. It doesn't buzz, it doesn't ask you to log a shot type, it doesn't try to be a coach while you're on court. One tap, back to the game. Afterwards the phone app gives you the full picture: break points, how you played under pressure, your form curve over the last months, and an AI coach that reads your matches and tells you what actually cost you the set. The second half is the one I'm most excited about: every match comes with a live score ticker you can share as a link. Your parents, your club mates or your team captain open it in a browser and follow the score point by point as you play. No app, no account, nothing to install on their side. Club teams have started using it for their league matches so the people who couldn't make it can still follow along. A few things I decided early on and stuck to: Free, no ads, no account. You install it and play. Kortscore Plus is a one-time purchase, not a subscription. It unlocks the detailed stats, automatic backup and the AI coach. Android and Wear OS only for now (Wear OS 3+, so Pixel Watch and Galaxy Watch 4 and newer). I get asked about Apple Watch a lot, more on that below if you're curious. I'm a solo developer from Vienna and I've been running this with local tennis clubs for the past months. The launch today is the first time I'm showing it to a wider audience, so I'd love honest feedback. What would make you actually wear a scoring app during a match, and what would make you take it off after one game? I'll be around all day answering questions.
