About
Everything is worked out on your device, with no internet needed: the Sun and Moon from Jean Meeus's and Paul Schlyter's formulas, the planets from JPL's approximate orbital elements (good to a fraction of a degree between 1800 and 2050), stars from the Yale Bright Star Catalogue (public domain, to magnitude 4.5).
Magnitude is brightness: lower is brighter. Venus can reach −4.5, Sirius −1.5, and the faintest stars you can see from a dark place about 6. A fist held at arm's length covers about 10° of sky. Rise and set times assume a flat, clear horizon. Your location is saved only on this device.
