Solar System vs Twinkleton

The whole Solar System, in motion, in your pocket. Watch eight planets sweep around the Sun in a live orrery, tap any world to open its full profile, and finally see how big — and how far apart — everything really is. Most space apps hand you a flat diagram or a wall of text. SolarMap gives you a moving map you can actually play with: pause the orbits, speed them up, then jump straight into real NASA and ESA figures for diameter, mass, gravity, day length, year length, mean temperature and moon count. Every world, every number and every photo is stored inside the app, so it all works with the phone in airplane mode. WHAT YOU GET - See all eight planets orbiting the Sun at true relative speeds, with pause and speed controls - Open a deep profile for 14 bodies — the Sun, every planet, Pluto, Ceres, the Moon, Titan and Europa - Compare worlds by size or by distance from the Sun and finally grasp the real scale - Read the numbers that matter: diameter, mass, gravity, day, year, temperature, moons, composition - Test yourself with a 10-question Solar System quiz that tracks your best score - Save your favorite worlds and pull them up instantly from the Explore tab PERFECT FOR - Curious minds who want astronomy explained without a textbook - Parents and teachers looking for a clean, ad-free way to show kids the planets - Students revising planetary facts before a test - Stargazers who want the science behind what they see at night WHY NOT JUST SEARCH ONLINE? A search gives you one number at a time, wrapped in ads, and never shows you motion or scale. SolarMap puts the whole system in one place — orbiting, comparable, sourced from NASA Solar System Exploration and ESA archives, and readable offline on a plane, a camping trip or a classroom with no Wi-Fi. PRIVACY No account, no sign-up, no ads, no tracking. Your favorites and quiz score stay on your device. The app makes no network requests for its content because all data and imagery ship inside it. FULL ACCESS The Sun, Mercury, Venus, Earth and Mars are free to explore. Full Access unlocks the gas and ice giants (Jupiter, Saturn, Uranus, Neptune), Pluto, Ceres, the Moon, Titan and Europa, plus faster orbit speeds, unlimited favorites, every Compare entry, all Learn articles and the Solar System quiz. Available as a weekly subscription, a yearly subscription, or a one-time lifetime purchase. Open the Orrery and tap a planet to start exploring.

Twinkleton is a gentle, beautiful astronomy playground for curious explorers (ages 5–10). Spin a real 3D solar system in your hands, sit back for a movie-like flight past every planet, and discover how space works through playful, hands-on lessons — all guided by Luma, a friendly little astronaut. EXPLORE IN 3D • A real-texture Sun, eight planets, Pluto, the Moon, Saturn's rings and the Milky Way • Drag to orbit, pinch to zoom — like holding the solar system in your hands • Tap any planet to fly to it and open a friendly fact card • Slow it down, speed it up, or rewind time to watch the planets dance A MOVIE OF THE SOLAR SYSTEM • Immersive mode plays a calm, cinematic fly-through — drifting in from far away, then visiting each planet up close with gentle music LEARN BY DOING Ten interactive lessons turn big ideas into simple play: • Why we always see the same face of the Moon • Why you float with a tiny jump on the Moon (1/6 gravity) • How far the Sun is — light takes 8 minutes to reach us • How many Moons fit inside the Earth • Which planet is hottest (surprise — it's not the closest one!) • How much you'd weigh on every planet • What a satellite is — natural vs. man-made • How long a day lasts on other worlds • Solar and lunar eclipses, seen from space AND from Earth • A deck of cosmic fun-facts SAFE, GENTLE & AD-FREE • Fully bilingual — English and 繁體中文, switch anytime • Friendly voice narration reads every fact aloud • No ads, no links out, and no sign-up — privacy-first, anonymous analytics only • Works on iPhone and iPad Distances and sizes are scaled down so everything stays fun and visible — a toy model of the real thing, built to spark wonder.
