Why Starly

A real sky, not a cartoon

Every star, planet and satellite is placed by the same astronomy the professionals use — then drawn to feel like wonder, not homework.

Your exact sky

Set your location and time and Starly shows precisely what is overhead — tonight, last birthday, or a century from now.

Tap anything to learn

Touch a star, planet or fuzzy smudge to get its name, distance, brightness and a story you will actually remember.

38 sky cultures

See the same stars as the Chinese, Arabic, Polynesian, Māori, Inuit and dozens of other peoples drew them.

Catch the ISS

Live satellite passes — including the International Space Station — so you can wave at the crew as they fly over.

The real Milky Way

A photographic galaxy, dimmed by real moonlight and city glow — so the sky looks like the one you can actually find.

Point and find

On a phone, hold it up and the map follows where you point — walk outside and let it guide your eyes to the target.

One sky, many stories

Travel the sky through 38 cultures

The constellations you grew up with are just one way of joining the dots. Switch traditions and the same stars become a Chinese imperial court, an Arabic herd of camels, a Polynesian voyaging canoe or an Aboriginal emu in the dark dust lanes — names kept in each culture's own words.
