I want to bring astronomy to everyone’s pocket through a polished, cross-platform mobile app that runs smoothly on both iOS and Android. The core of the project is solid, well-referenced scientific content—planets, stars, galaxies, and current phenomena—presented in language a curious beginner can grasp without diluting accuracy. I already have a content outline and source material; your job is to translate that into an engaging experience. Functionally, the first release must include at least one interactive diagram or simulation that lets users explore orbital mechanics or stellar life cycles in real time. I am open to adding sky-map style views or short animations later, but for now those are only nice-to-haves. What matters most today is a clean, modern UI, fast load times, and architecture that leaves room for easy feature drops in future updates. You should be comfortable recommending and executing the full stack—whether that means Flutter, React Native, or native Swift/Kotlin—so long as the end result stays maintainable and performant. I take UX seriously, so show me examples where you have balanced heavy data with intuitive design before. Deliverables for this milestone • A fully functional mobile app submitted to TestFlight/Google Play Internal Testing • One interactive diagram or simulation feature, complete with touch gestures and concise tool-tips • Structured data layer (local or cloud-sync capable) that can be expanded with new objects and events • Brief technical documentation outlining architecture, deployment, and next-step recommendations If you thrive on turning complex science into beautiful software, I’d love to hear how you would tackle this build and what technology stack you suggest.
