Whats Up!

Whats Up! turns your phone into a live sky guide. Point the camera at the night sky to identify stars, planets, constellations, satellites, and deep-sky objects. Find targets with on-screen guidance, plan naked-eye visibility, and get reminders for bright passes like the ISS — including when they’re actually illuminated and worth stepping outside for. Features • Live AR sky view with a night-vision friendly UI • GPS + sensor pointing for accurate sky direction • Offline catalogues for stars, Messier objects, and constellations • Sun, Moon, and planets with local ephemeris • Satellite passes (including ISS) with visibility-aware alerts • Optional live aircraft overlay when online • Meteor showers, time travel, sky planner, and a solar-system tour • Voice guide and read-aloud for many objects Permissions • Camera — AR sky preview • Location — sky math, pass times, and local conditions • Notifications — optional visibility reminders • Internet — optional satellite TLE, weather, and aircraft updates Works best outdoors under a clear sky. Catalogue positions are for navigation and learning — not professional surveying.
