Updated for iPhone Duo. Closed, folded or flat, upright or sideways, the layout follows the screen, and nothing you read or tap ever sits in the crease. Closed, the controls move into a column at the side, so the planets get the full height of the cover screen. Half open like a book, a world's dossier gets its own page while the orrery keeps the other. Stood up like a laptop, the orrery sits on top and the dossier below. Laid flat, the whole solar system spreads across the inner screen. On every other iPhone, iPad and Mac, The Grand Orrery looks and works exactly as before.
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.
