Astra
Point your phone at the sky and instantly name every star, planet, and constellation.
A calm, gorgeous star map for the rest of us. Raise your phone to the night sky and Astra names what you're looking at before you've steadied your arm — stars, planets, the Moon, the 88 constellations, even the ISS as it slides overhead. Tap anything to learn its story, save what you've spotted, and let the sky become familiar.

Astra was built for exactly this.
The core features that make Astra different from the generic alternatives.

raise your phone and Astra labels the star, planet, or constellation in front of you in real time.

Tonight's sky
the brightest objects visible from where you're standing right now.
A sky journal of everything you've spotted, so the night sky slowly becomes familiar.
Time travel (Pro)
scrub the sky to any date and time to plan a meteor shower or replay an eclipse.
Event alerts (Pro)
a quiet nudge before the ISS passes over, a shower peaks, or planets meet.
A note from the studio
“I grew up able to name maybe three things in the sky, and I assumed real stargazing required gear I'd never buy. Astra is the app I wish I'd had on the first clear night I spent away from city lights — it doesn't lecture you, it just quietly tells you what you're looking at until, one night, you realize you already know.”
