Twinkleton vs Solar Journey

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.

FOLLOW REAL MISSIONS Replay selected historical spacecraft journeys reconstructed from archived trajectory data. The MESSENGER replay is included free. These are historical replays, not live spacecraft feeds. KEEP A FLIGHT LOG Save completed journeys in an on-device Flight Log and share a flight card. The log keeps your most recent 100 completed journeys. START FREE, EXPLORE FURTHER The guided Earth-to-Moon journey and MESSENGER replay are free. A one-time Full Access in-app purchase unlocks Mars, additional destinations and mission replays, and advanced controls. No subscription. Some journeys and optional visual or scientific assets may require a download and an internet connection. Solar Journey is an educational spaceflight experience. Its cockpit takes visual inspiration from the Apollo era; it does not simulate an Apollo lunar landing. Planned journeys use models and disclosed approximations and are not intended for real spacecraft navigation. Data-source credits in the app do not imply agency endorsement.
