Pie Matrix - Sky Map

Point your phone at the sky and see stars, planets, constellations, and satellites in real-time AR. Track tonight's best objects with your telescope. Free to explore.

Pie Matrix turns your iPhone into a real-time window to the cosmos. Point your phone at the sky and instantly see what's above you — stars, planets, constellations, the Moon, deep sky objects, and even the ISS flying overhead.

AUGMENTED REALITY SKY VIEW Hold your phone up and the sky map aligns perfectly with what's above you using your device sensors. See 190,000+ stars rendered in real-time with accurate positions, colors, and brightness. Watch constellations come alive with artwork overlays.

WHAT'S VISIBLE TONIGHT Every evening, Pie Matrix computes what's visible from your exact location — bright planets, the Moon's phase, Messier objects, meteor showers, and satellite passes. No guesswork, just look up.

SEARCH & FIND ANY OBJECT Looking for Saturn? The Andromeda Galaxy? Type its name and a guided reticle points you right to it. The circle shrinks as you get closer — satisfying every time.

MY TELESCOPE Select your telescope from our catalog and get personalized observing targets based on your equipment's capabilities. Know your magnification, field of view, and faintest star visible — then find objects matched to your setup.
