Starlore — Learn the Night Sky

Starlore is not a planetarium. It is an observing passport: you confirm what you actually saw in tonight's sky, log it, and move up through the stages. ■ Tonight Astronomical twilight, the Moon, planets, meteor showers and sky brightness (Bortle class) for your location, on one screen. It picks the tasks you can do tonight. ■ Sky Raise the phone and 80,000 stars, constellation lines, the ecliptic and the Milky Way appear in that direction. If the compass drifts, tap a bright star to align. ■ A six-stage passport Moon Keeper, Constellation Hunter (15), Planet Tracker, Meteors & Events, Binocular Objects, Messier Silver. Align a field task in AR, tap Seen, and the time, azimuth, altitude and sky brightness are logged for you. Clouded out? Indoor tasks keep you going: quizzes, simulators and sketch comparison. ■ Observing journal Equipment, seeing, transparency, notes, photos and sketches. List, calendar and life-list views, with CSV (Astronomical League log-sheet columns) and PDF export. ■ 24 learning cards Short cards written for ages 10 to 14, from watching the night sky to the solar system, stars and the universe. ■ Red-light mode Zero white pixels, capped brightness, battery saver. It protects your dark-adapted eyes. Starlore is fully offline. No ads, no subscriptions, no analytics SDKs, no accounts. Your location never leaves the device. Stages 0 and 1 are free.
