Almost everyone can find the Big Dipper, and almost nobody can name what sits next to it. Starlore closes that gap: a calm, offline atlas that turns a scatter of dots overhead into figures you can recognise and then remember.
Each constellation is drawn on a living starfield. Stars glow and gently twinkle, sized by their real brightness, joined by faint lines that trace the figure, with the brightest star picked out and named. Open one to find what its name means, which hemisphere and season it belongs to, whether it's one of the zodiac, and the story behind it, retold in plain language rather than dense astronomy.
Best of all, every entry carries a down-to-earth "how to find it" tip: the kind that starts from a landmark you already know and walks your eye across to the target.
The Spot-It quiz
A bare figure appears and you name it, or you're asked about seasons and myths. The answer is revealed each time, so the quiz teaches as you play.
Seen with your own eyes
Mark only the constellations you've genuinely picked out of a real sky, and the progress ring fills over months rather than minutes.
Browse the whole sky by hemisphere, by season or by zodiac sign, and search by name. Tune the twinkle, switch the connecting lines off, choose an accent colour. Completely offline, no account, no ads, ready on a dark hillside or on the sofa.

Two notes. The myths are told as stories that people have attached to these star patterns for thousands of years, and the zodiac is here as a way the sky has long been divided, not as a claim about anybody's life. And the practical one: going somewhere dark is half the pleasure, so tell someone where you're headed, take a torch with a red mode, watch your footing more than the sky, and don't stargaze from a roadside.
The North Star is only on duty for a while
Earth spins like a slowing top, and its axis traces a slow circle in the sky: one lap in about 25,772 years. The circle has a radius of 23.44°, the tilt of the axis, drawn around the pole of Earth's orbit. Whichever bright star happens to sit near that circle at your moment in history gets called the pole star. Drag through the centuries and watch the job change hands.
Polaris is having an unusually good run: it comes closest around the year 2105, at 0.46° from the pole, which is about the width of the full Moon. Around 2830 BCE the honour belonged to Thuban in Draco, which got closer still, to roughly 0.2°. In between, near 1000 BCE, nothing bright was near the pole at all; Kochab was the nearest at over 6°, and sailors made do.
Looking forward, Errai in Cepheus takes over about the year 4100 at roughly 1.9°, then Alderamin near 7500 at 2.4°, and Vega comes back around 13,800, a bright but distant pole star at close to 4.8°. The numbers here are computed live from each star's position, precessed around the circle.
What's not here: no constellations, no figures, no myths and no quiz. This uses only the steady part of precession and today's star positions, so it ignores proper motion, which really does shift stars over thousands of years, along with nutation and the slow drift of the obliquity. It's a sketch of a mechanism, not an ephemeris. The sky itself, drawn figure by figure, is in the app.

If a "how to find it" tip doesn't work from where you stand, that's worth telling us: southern skies especially need local wording. Send the constellation and roughly your latitude.
