Twinkleton vs ORBITARIUM

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.

ORBITARIUM is a native astronomy app for iPhone and iPad that lets you explore the Solar System now through interactive 3D graphics and on-device astronomical calculations. Move through time and see planetary positions, day and night on Earth, axial-tilt seasons, and lunar phases update together in one coherent view. KEY FEATURES • The Sun, all eight planets, and the Moon in an interactive RealityKit scene • Drag, pinch, and tap to orbit, zoom, and focus on celestial bodies • Select a date, play or pause time, change speed, and move across a four-year range • Earth's day-night boundary, city lights, clouds, and atmosphere synchronized with sunlight • Northern and Southern Hemisphere seasons explained through axial tilt • Moon phase, illumination, age, and the next principal phase • Local time, solar altitude and azimuth, sunrise, and sunset for nine locations worldwide • Japanese and English localization • No account required; core features work completely offline Planet positions and astronomical events are calculated on device. Body sizes and distances are compressed or exaggerated for educational readability and are clearly identified in the app.
