9月8日 的 The Grand Orrery 應用程式分析

No subscriptions. No ads. No accounts. The whole solar system. The Grand Orrery is a hand-built model of our solar system, drawn in the style of an antique astronomical atlas and powered by a native Metal renderer. Twenty-five worlds — the Sun, every planet, Pluto, and fifteen notable moons — spin and orbit in real time. Tap any of them and the camera sweeps you to its sunlit side while its field-guide dossier slides up: measurements, atmosphere, notable moons, and the kind of margin notes an astronomer would actually tell you at the eyepiece. Every world's surface is generated on your phone — except Earth, which wears NASA's own Blue Marble portrait — and every figure in every dossier was verified against NASA and JPL references, with the sources one tap away. - Pinch, drag, and fly through a living orrery rendered at up to 120 fps - Field-guide dossiers for 25 worlds, checked against NASA and JPL - The Grand Tour: sit back while the orrery visits each world in turn - A quiet, generated ambient soundscape (leave it on or switch it off) - Orbit lines, floating labels, adjustable time — from hours to years per second — and a pause button when you just want to look - Sources for every world, cited in the app - Works completely offline; collects nothing Buy it once. Keep the solar system in your pocket.
