Galactic Compass is a beautiful, sci-fi-inspired utility that calculates and visualizes your real-time astronomical direction and speed through space. Ever wondered how fast you are actually moving right now? Galactic Compass integrates your device's compass, gyroscope, and GPS to orient you toward major cosmic points and breaks down your motion across multiple reference frames. Key Features: • Earth's Rotation: See how fast you are moving east just by standing on the spinning Earth. • Solar Orbit: Track the direction of our solar system's journey around the Sun. • Galactic Center: Point toward the supermassive black hole at the center of the Milky Way and visualize our galactic orbit. • Andromeda Galaxy: Locate our neighbor Andromeda and track our mutual approach speed. • Great Attractor: Orient yourself toward the mysterious gravity well pulling our entire galactic group through the universe. Features a stunning retro-future sci-fi vector HUD UI, real-time sensor integration, offline calculation, and a built-in sensor calibration screen.
