About StargazerLog: Constellations
StargazerLog tells you what's happening in the sky above you tonight — real stars, real constellations, real math. Computed on your device from genuine astronomical catalogs, accurate anywhere on Earth. WHAT IT DOES • Tonight's constellations: which of the 88 constellations are up right now, which direction to face, and how high to look — built on a catalog of the brightest real stars (Sirius, Vega, Orion's Belt and more). • Constellation finder: tap any constellation for its star chart, brightest stars, and how to spot it. • Stargazing score: a 0–100 rating of tonight's sky conditions — moonlight, darkness windows — so you know if it's worth heading out. • Meteor showers & sky events: Perseids, Geminids and every major annual shower with real peak dates, plus full moons — see what's coming in the next 30 days. • Moon phase now: current phase, illumination, and moon age at a glance. • Planets tonight: which of Mercury, Venus, Mars, Jupiter and Saturn clear the horizon after dark — and where to look. • Nightly reminder: an optional "Tonight's Sky" notification with what's visible after dark. BUILT ON REAL DATA Star positions come from the Yale Bright Star Catalogue, constellations from the official IAU 88, meteor shower dates from the International Meteor Organization — all computed with deterministic astronomy on your device. No accounts, no guessing, no made-up data. SET YOUR LOCATION Pick a city or enter your exact latitude and longitude, and the whole sky is recomputed for where you actually are. STARGAZERLOG PLUS Core features are free. StargazerLog Plus unlocks every constellation tonight, search, and the 7-Day Sky Ahead — a week of nightly moon phases, the best planets to spot each night, and the darkest sky for stargazing.

Subscription: auto-renews unless canceled ≥24h before the period ends; payment charged to your Apple ID at confirmation; manage/cancel in App Store settings.
