"What is that star?" — Find the constellations directly above your head right now.

Have you ever wondered while looking up at the night sky?

When you open the app, the stars and constellations currently in the sky are instantly displayed on a circular star chart based on your current location (GPS) and time. There are no complicated settings or sign-ups required.

■ The Sky at a Glance

The zenith is in the center, and the horizon is at the edge. It displays 17 well-known constellations—such as Orion, the Big Dipper, Cassiopeia, and Cygnus—along with bright stars, planets, the moon, and the sun, exactly as you see them.

■ The Sky Follows You When You Turn Your Head

With compass integration, the star chart rotates in real-time to align with the direction you are facing. The cardinal directions (East, West, North, South) are also displayed, making it easy to match with the actual sky.

■ Point Your Camera and the Constellations Right There

When you point your camera at the sky, the constellations in that direction are superimposed on the screen. You can turn the overlay on and off with a single button.

** ■ Tap to Tell a Star

Tap a star or constellation to reveal a card containing its name, brightness, and story.

■ Location-Based · Offline Calculation

All celestial positions are calculated directly on your device. It works without data connectivity.

Look up at the sky right now and instantly identify that star. ✦
