With your location and the time, see exactly what is in the sky right now. 246 bright stars and constellation lines drawn from real coordinates.
Using the orientation sensor and your location, the sky you are facing is drawn on screen. No camera — a phone cannot expose long enough to capture stars, so the frame would be nearly black.
Every star brighter than magnitude 4.0, placed by J2000.0 coordinates. Size follows brightness, colour follows spectral type.
Phone magnetometers are often off by 10–30 degrees. Align a bright star on screen with the real sky to correct.
