Serendip Moments - Reconnect with strangers who shared your moment

Hey Product Hunt 👋 I'm Enrique, and I built Serendip Moments solo over the past few months. The idea started from a very simple, very human feeling: sometimes we share a moment with a complete stranger — a look on a train, someone who helped us and vanished before we could say thanks, a pet we found but couldn't keep — and there's never been a way to find that person again. Serendip is a global map where you drop a pin on the exact place and time something happened. If the other person does the same, the app connects you. You can mark something from the Past, something happening right now, or something in the Future (like "I'll be at this festival, anyone else?"). This is a real beta — I've built and tested it mostly alone. It currently works in English, Spanish, and Russian, a few other languages are partially translated, and you might hit the occasional rough edge. The moments you'll see on the map right now are seed/test data I created myself while building — there's no real community yet. You'd genuinely be among the first real ones. I'd love to hear: - What's confusing in the flow (publishing, matching, chat) - What type of "moment" you wish existed - Anything that looks broken Thanks for taking a look 🙏
