Star map, northern lights forecast and night sky guide. Free, offline, no ads. Point your phone at the sky and see what's there — stars, planets, constellations, the northern lights. Starmap works completely offline, anywhere, with no signal. Built by a professional astronomer and given freely. No ads. No subscriptions. No in-app purchases. No tracking of any kind. Everything is unlocked from the first launch. AURORA AND NORTHERN LIGHTS Live aurora forecasts from NOAA, with the Kp index, the three-day outlook and the auroral oval for both hemispheres. Know whether tonight is worth staying up for. OUT WITH THE FAMILY Hold the phone up and it names whatever you're looking at. An arrow guides you to any planet, star or constellation. Every catalogue is stored on the device, so it works in the mountains, at sea, or anywhere without a signal. THE SUN AND THE MOON Sunspots, flares and X-ray flux, live from NOAA. 9,900 named lunar features with their origins and etymologies. Rise, transit and set times for everything, which you can send to your calendar. FOR SERIOUS OBSERVERS 2.5 million stars stored offline, down to magnitude 15. The full Messier, NGC, IC and Caldwell catalogues, plus Sharpless, van den Bergh, Lynds, Barnard and Abell clusters. Live comets, asteroids and trans-Neptunian objects from the Minor Planet Center. Deep-sky records enriched on demand from SIMBAD, searchable by any catalogue identifier. AT THE EYEPIECE Define your telescope, eyepieces and camera, and see the true field of view you'll actually get, with Telrad rings and reticles. A full red night-vision mode for use in the dark. The whole sky in your pocket — free, because that is what it should be.
