An orrery is a mechanical model of the solar system. This is yours, alive in light. Open the app and fly: all eight planets, Pluto, the Moon, and a working asteroid belt orbit a glowing Sun in real relative motion. One finger orbits the camera, a pinch zooms, and a tap on any world glides you to its sunlit side. Earth, Moon, and Sun are free to explore in full. One purchase unlocks the whole solar system. No subscription, no ads, no accounts, ever. EXPLORE Every world has a full page: a spinnable globe, NASA-sourced vital statistics, an animated size comparison, and a "Did you know?" carousel. LISTEN A narrated story for every world, written from NASA sources. THE GRAND TOUR An eleven-stop guided cruise from the Sun to Pluto. TIME TRAVEL One switch sets every world where it truly is right now, computed on device from JPL planetary theory. Then visit the moments that made history: Neptune's discovery night (1846), Apollo 11 (1969), Voyager 2 at Neptune (1989), New Horizons at Pluto (2015). YOUR SKY Choose a day that matters and the whole orrery travels to it. The planets move to where they truly stood, and the day becomes a card you can keep or share: the phase of the Moon, the constellation the Sun was crossing, and two lines written for that sky alone. ON YOUR HOME SCREEN A living miniature orrery widget, every planet in its true position, plus a world of the day with a fresh fact each morning. STARGAZER SCHOOL Seven illustrated mini lessons on the big questions. Why days and years happen, why Pluto isn't a planet anymore, the farthest we have ever traveled, how telescopes see back in time, living in space, Hubble and Webb, and the Space Station overhead. Interactive diagrams and real NASA photography. THE COSMIC QUIZ Five fresh questions every run, drawn from sixty. IN YOUR ROOM Place the solar system on your table with AR. Toggle true distances and walk to Neptune. SPEAKS YOUR LANGUAGE English, Spanish, French, Simplified Chinese, and Vietnamese. Follow your device language or switch right in the app; every story is narrated in every language. TRUE SCALE One switch spreads the orbits to real relative distances. Space is unimaginably empty; feel it. Built for curious kids and the adults who point at the sky with them. Fully supports VoiceOver, Dynamic Type, and Reduce Motion. Collects nothing, tracks nothing.

Verdict
The clearest difference is price: Orrery at Free against 3D Elements's $1.99. Orrery also leads on update cadence (every 5 days vs every 4 months). 3D Elements's advantage is in-app purchases (none vs 1). On ads, device support and iOS requirement there is nothing between them.
