Point your phone's camera at a canyon wall, a mountain peak, or any part of the sky. A crosshair marks the center of the frame, and live readouts show exactly where it's pointing — compass direction and degrees above the horizon. Glowing markers float over the live view pointing to Polaris and the brightest stars — Vega, Deneb, Altair, and Arcturus — so you can find your bearings and learn the sky.
