What Skymap does
Everything you need to know the night sky — without owning a telescope, a star chart, or a single equation.
Point at the night sky. Constellation lines, planet labels, and star names appear over what's actually there — no calibration, no setup, no charts.
See where every visible planet sits in the sky right now — from your exact location.
Every IAU constellation with classical line patterns, mythological origin, and the brightest star in each.
Fast-forward or rewind. See where Mars will be tomorrow, or where Polaris stood 10,000 years ago.
Each constellation tells two stories: the Greek myth that named it and the modern physics that lights it. Read either, or both.
After download, Skymap works without a signal. Desert sky, mountain cabin, transatlantic flight — it's all yours.
The Drawing.
Humans have been connecting these dots since before language. Skymap shows you the exact pattern that Sumerian astronomers, Polynesian navigators, and Greek poets all saw in the same sky.

The Science.
Every photon that hits your eye from a star left it before you were born. Light from Polaris began its trip when Henry VIII was crowned. Light from Andromeda was sent before Homo sapiens existed.
Skymap doesn't show you the sky. It shows you a 4D snapshot of the sky — space and time, intertwined, on a screen the size of your palm. We think that's worth pointing at.
