Twinkleton vs Cosmivoy

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.

Explore the sky above you. Fly to the worlds beyond it. Cosmivoy turns your iPhone or iPad into a spaceship window. Discover the Solar System in 3D, travel from Earth to distant galaxies, and choose your own view of the universe. • See the sky from your location and look around by turning your device. • Warp between planets, orbit a moon, or land and explore a rocky world's surface. • Follow satellites and deep-space missions, including Webb and Voyager. • Pause, rewind and fast-forward time to explore orbits, sunrises and eclipses. • Zoom from a close-up to a 360° panorama. Switch between natural light and fill light to reveal surface details. • Read an offline encyclopedia and explore a catalog of more than 100,000 stars, Solar System bodies, galaxies and spacecraft. Core exploration works offline, without an account. Satellite orbit updates use an internet connection. Interface and encyclopedia available in 14 language options. No ads, subscriptions or in-app purchases.
