About Gnomon - Sun Path Tracker AR
GNOMON is an AR sun and moon path planner. Point your phone at the sky and see exactly where the sun will rise, travel and set, drawn over your camera view, before it happens. The gnomon was the first sun instrument in human history. This is yours. EVERYTHING IS COMPUTED No estimates and no fake data. GNOMON runs a full onboard ephemeris and computes every azimuth, altitude and event time from real astronomy for the exact place you are standing. Sunrise, solar noon, sunset, golden hour, blue hour, moonrise and moonset are all calculated on your device. SEE THE LIGHT BEFORE IT ARRIVES - The full sun path drawn over your camera, with past and future arcs - Live azimuth and altitude readout as you move your phone - A compass ruler with cardinal directions on the horizon - Event markers for sunrise, golden hour, noon, sunset and blue hour - A 24 hour time scrubber, drag it to preview the sky at any minute of the day - Tap any event to jump straight to that moment - Notifications before golden hour and sunset so you never miss the light MADE FOR PEOPLE WHO CHASE LIGHT Photographers planning a shot. Filmmakers scouting a location. Architects reading shadows. Or anyone who simply wants to know where the sun will be at 7 in the evening. CALIBRATED LIKE AN INSTRUMENT A quick compass calibration and a fine alignment step let you drag the on screen marker onto the real sun, locking the overlay to the sky in front of you. GNOMON PLUS Upgrade to unlock the full instrument: - Moon mode with the full lunar path, phases, illumination, moonrise and moonset - Date travel, preview the equinoxes and solstices and plan months ahead - MIL angle readouts in NATO 6400 for precision work Your location and camera feed never leave your device. Nothing is recorded and nothing is uploaded.
