Point your phone at the night sky and know exactly what you're looking at. SkyDial is a star and planet finder built around one idea: the sky map is only as good as its pointing. Phone compasses drift, and cars, magnetic cases and railings throw them off by 10° or more. SkyDial lets you fix it in seconds. Aim at one bright star, confirm which one, and it corrects the error and follows you by gyroscope from there. IDENTIFY • Live sky with labelled stars, constellations, planets, the Moon and the Sun • Tap any object for its name, catalogue number, magnitude, distance, spectral type, colour and tonight's rise and set • Find mode guides you to any object with an on-screen arrow • Real star colours: blue Rigel, orange Betelgeuse EXPLORE • Time scrub: move hours, days or years and watch the sky turn • Tonight: the Moon's phase and what's up, for indoor and cloudy evenings • Constellation lines, labels and IAU boundaries • Guided tours: star colours, real distances, planets versus stars, changing stars and the Nakshatra • Optional camera view behind the sky map SEE WHAT YOU CAN SEE • Set your Bortle light-pollution class and the map shows only what your sky allows • Night vision mode: a red display that protects your dark adaptation, dimmed automatically after dusk HONEST AND SAFE • Magnetic interference warning tells you when the compass can't be trusted • Sun warning before you point at it PRIVACY Location stays on your device. You can enter a city instead of using GPS. Requires an iPhone with motion sensors. Made by RIGPA Tech.
