Store description excerpt
A living orrery for Apple Watch. All eight planets orbit in real time — no internet, no iPhone required. Open the app and every planet snaps to its actual position for today, calculated entirely on-device using Keplerian orbital mechanics. Time flows forward automatically, one month per second, so you can watch the solar system breathe without touching a thing. **Explore in any direction** Turn the Digital Crown to travel through time — forward or backward, to any moment in history or the future. Drag anywhere on the screen to tilt your view into 3D and rotate freely. Release and the camera keeps spinning with natural inertia, gliding to a stop like floating in space. Double-tap to return to the default top-down view. **Zoom in** Long-press the screen to glide the camera toward the sun. The longer you hold, the faster it moves. Release to hold your position, then drag to look around from there. **Planetary textures and a star-filled sky** Each planet is rendered with NASA-based imagery — Jupiter's bands, Mars's rust, Earth's continents — against a backdrop of the Milky Way. Fading orbital trails trace each planet's recent path. **Fully offline, always** No network connection. No iPhone. No account. Just open it and it works.
