DNA Seed gives every player a digital DNA that is unique in the world — no two will ever be alike. Trade it by scanning QR codes with players you meet in real life. Then it travels without you: everyone who carries your signature can pass it on, so a trade in Geneva can take it to Tokyo. Track your DNA on the world map as countries light up, collect the signatures you cross, unlock 100 badges, and climb country, region and team rankings. Free on iPhone (Android coming soon).

Hi Product Hunt! 👋 I built DNA Seed around a simple question: how far can something uniquely *yours* travel without you? When you sign up, the app generates a DNA signature that exists nowhere else in the world. You can only trade it in person, by scanning another player's QR code — no remote sharing, no shortcuts. After that, your DNA has a life of its own: every carrier can pass it on, and you watch it hop from person to person, country to country, on the world map. It's part social game, part real-world collectible. There are 100 badges to earn (countries reached, validated meetings, propagation depth…), team and country rankings, and a directory of every signature you've crossed. The game just launched clean on the App Store, so early players are literally the first DNA strands in the network — perfect time to start spreading. I'd love your feedback, and if you try it: tell me how far your DNA gets! 🧬
