Watch how the modeled sky changes, show or hide constellation lines, and tap solar-system objects to learn more. No camera or location permission is needed. MEET THE LIVE SKY On supported iPhones and iPads, use the rear camera, location, and motion sensors to view an approximate sky overlay. Tap a planet or constellation for its educational card. Adjust heading alignment when nearby magnets or compass interference cause an offset. PRIVATE BY DESIGN All astronomy calculations and learning content run on your device. Camera images, location, and motion data are not uploaded or shared by Epicycle. Learn, Explore, the quiz, and the sky map work offline without camera or location permission. Explore outside with a grown-up and stay aware of your surroundings. Never look directly at the Sun or point binoculars or a telescope at it. Sky positions are educational estimates; visibility depends on daylight, weather, buildings, and light pollution. Camera alignment depends on the device’s sensors.
