Everything that decides a night, on one screen: sunset and sunrise, moonrise and moonset, tonight’s phase, the temperature an hour after sunset, and hour-by-hour cloud cover. Step through any date you like.

A calendar of moon phases, true-dark windows, weather, planet positions, and the night's best deep-sky targets — tuned to your saved location. Cloud-cover forecasts blend three global weather models (ECMWF, ICON and GFS) through the Open-Meteo service; moonrise, moonset and astronomical-twilight times are computed on your device.

The constellations, the planets, and the deep-sky wonders — a single hub for everything you can point a scope, binoculars, or your eye at tonight. 36 constellations and 13 asterisms, the planets with live positions for tonight, and a deep-sky catalog spanning Messier, Caldwell, NGC, and IC objects, ranked by how high each climbs tonight.

Interactive maps of the darkest stargazing spots across Utah's Big 5 — Zion, Bryce, Capitol Reef, Canyonlands, Arches — plus Cedar Breaks. Bortle-rated overlooks, trailheads, and remote sites with GPS-aware "you are here" markers and detailed info for each location.

The year's meteor showers and headline celestial events — oppositions, eclipses, conjunctions, solstices and equinoxes — each counted down to the night. Every date is computed and cross-checked against two independent ephemerides, with the Moon’s interference noted for each meteor shower.

Aim your phone's camera at any peak or patch of sky and read the exact compass direction and altitude — for planning where the Milky Way or moon will rise. Live AR overlay aligned with the phone's magnetometer and accelerometer, calibrated for true (not magnetic) north.
