Hey Product Hunt! 👋 Solo developer from India here. After publishing PayWise (a personal finance app) and a few enterprise apps, I wanted to build something I'd actually use myself and I've always been obsessed with space. Cosmic Facts started as a hobby to browse NASA's APOD daily. Six months later, it's 50+ features: 🛰️ Live ISS tracking with real orbital telemetry 🌍 Daily Earth photos from DSCOVR satellite (1.5M km from Earth) 🪐 Interactive 3D Solar System (Three.js inside Flutter WebView) 📐 Orbital mechanics calculators, escape velocity, Hohmann transfer, time dilation, with formulas explained 🔭 6,000+ confirmed exoplanets from NASA Exoplanet Archive ☄️ Near-Earth asteroid tracker 📚 84 lessons across 12 topics + 200 quiz questions The hardest parts: - Getting Three.js to work smoothly in Flutter WebViews - Handling 7 NASA APIs with proper caching + offline fallback - Designing a "Mission Control" aesthetic for live data without clutter Free forever, no ads, no signup. Built solo in evenings and weekends. Would love feedback, especially what features you'd want next. Happy to answer technical questions about the Flutter + Three.js setup.
